It has been customary in the field of obstetrics for all pregnancies to be dated from the woman’s most recent menstrual period. This is a practice that dates back hundreds of years.

After the 40th week of gestation, after the first day of the woman’s most recent menstrual period, most pregnancies are regarded to be full-term and ready for childbirth.

Since we know the date of conception, which is the day of egg retrieval and insemination, we can calculate a hypothetical last menstrual period following an IVF conception. This gives us the date of the woman’s last menstrual period.

Why Am I Spotting Or bleeding?

Find common bleeding reasons below.

Note that minor bleeding, spotting, or cramping is normal, but heavy bleeding like menses or more should be reported to the doctor because it may indicate a problematic pregnancy. 

Early Pregnancy Monitoring

Bleeding during an IVF pregnancy at 6 weeks can be concerning but isn’t uncommon. It may be due to implantation bleeding or other causes. It’s crucial to notify your healthcare provider promptly to rule out any serious issues and ensure the well-being of both you and your pregnancy.

Given the patient’s journeys, a positive pregnancy test is thrilling. We will monitor pregnancy until 10 weeks until our patients start consulting their obstetrician.

The patient will receive intra-vaginal progesterone tablets or injections for the first 7 weeks of pregnancy. After that, age, ovarian health, and embryo determine their care.

The initial ultrasound checks for embryo attachment and heartbeat. Another ultrasound monitors embryo growth and development. We will discharge the patient when the second ultrasound shows satisfactory viable fetal growth and cardiac action.

We can recommend patients to any of our top obstetricians if they don’t have one. We can also help with prenatal genetic screening and testing. 

How do I evaluate early pregnancy bleeding?

Some tests might help you determine the severity of bleeding in early pregnancy. First, there’s no need to freak out. Pregnancy can be confirmed with a urine or blood test after spotting or light bleeding in the first few weeks of pregnancy.

Ultrasound of the uterus or vagina verifies the pregnancy. The risk of having a miscarriage increases after age 40.

If a healthy heartbeat can be seen in the initial ultrasound, everything is well. After a week, if you don’t feel the baby’s presence baby, a second ultrasound will be performed. Here, the chance of miscarriage is more than 50%.

A blood test can determine your blood type. If your red blood cells do not contain any protein, you are RH-negative. D-immunoglobulin shots will then be required to prevent future pregnancy complications.

What Causes Bleeding in IVF Pregnancy?

Causes of first-trimester bleeding include

Implantation bleeding

Embryo implantation into the uterine lining is followed by a short period of bleeding. In order to connect to the mother’s blood supply, the placenta must first implant itself into the uterine lining.

During this time, the placenta expands fast and produces a great deal of blood. Light bleeding may be the result of a ruptured blood vessel in the uterus.

The bleeding that occurs during implantation seems faint and has a pinkish or brownish hue. Normal post-implant bleeding lasts a few days. Mild cramps and breast tenderness are two other pregnancy symptoms that may accompany it.

Subchorionic Hemorrhage

Subchorionic bleeding occurs when the placenta separates from the uterine wall in a very small way. Blood can sometimes be seen collecting between the placenta and the uterus during an ultrasound.

Eventually, the bleeding will stop and some of the blood will leak out of the uterus. Most subchorionic hemorrhages are minor and heal on their own.


Cervical and endometrial polyps are often harmless growths. They tend to go unnoticed since they occur so frequently in the reproductive system.

However, hormonal changes during pregnancy might cause them to swell, making them more prone to bruising and bleeding.

Vaginal/Cervical Irritation

Frequent vaginal examinations, tampon use, sexual activity, etc., might irritate the vagina and cervix, causing minor bleeding. Repeated transvaginal ultrasounds have been linked to an increase in bleeding.

How Much Bleeding Is Normal After IVF?

Light spotting (pinkish or brownish) or bleeding is common after an IVF embryo transfer. Seeing a tiny bit of bright red blood is also not out of the ordinary. This bleeding is usually extremely light and stops on its own.

When Should I Be Worried About Bleeding During Pregnancy?

Heavy bleeding is described as soaking through one standard-sized pad in an hour, at which point you should seek medical attention. Other indicators of substantial blood loss that warrant a trip to the emergency room include extreme discomfort in the belly, weakness, nausea, vomiting, difficulty breathing, and chills. Rupture of an ectopic pregnancy can also cause unexplained shoulder pain.


The risk of bleeding following an embryo transfer using in vitro fertilization (IVF) is real. The good news is that the vast majority of these bleeding are really mild and harmless. Consult fertitliy hospital, if you suffer any bleeding ivf during early pregnancy, but know that the majority of cases will stop on their own.


IVF pregnancies frequently have uterine bleeding in the first trimester. The good news is that miscarriages and other negative consequences have not been proven to be more common as a result. According to general statistics, one-fourth of pregnancies experience vaginal bleeding during the first trimester.

Ovarian stimulation: During the earliest phases of IVF treatment, fertility medications will be used to stimulate the ovaries. As their hormone levels change, women may have light bleeding or spotting, just as they may in the days leading up to their period.

After 12 weeks of pregnancy, IVF is typically regarded as safe. When the first 12 weeks go smoothly, the chances of a successful pregnancy rise to 70–80%, making it as safe as natural conception. You can have a healthy kid with IVF treatment.
