Understanding the Mechanism of Implantation Bleeding

Implantation bleeding or period? Women often ask this question with hope or fear, in regards to whether hypothetical pregnancy is desirable at the moment or not. Actually, implantation bleeding is nothing else than a scanty bloody discharge of pinkish or brownish color. It occurs not in every woman and lasts normally just for a couple of hours.

Implantation bleeding is one of the earliest pregnancy signs, revealing itself even before you can notice that your period is late. Let`s investigate how pregnancy starts from the very beginning and we`ll better understand the whole topic.

Impregnation may happen during ovulation or right after it. This day, when you are the most fertile, normally starts in the middle of the cycle. For example, if your menstrual cycle is 30 days, ovulation occurs on the 13th – 16th day. About 10 days more are needed for the mature ovum to migrate through the Fallopian tubes into the uterus. Therefore, the process of the ovum’s embedment into the uterine wall can begin approximately on the 23rd – 28th day of your menstrual cycle. As a result, implantation spotting is possible a few days prior to the date of your period in the current month. This is why you can take it for early menstruation.

The first thing you must know is that implantation bleeding is a normal phenomenon for the female organism and the first symptom, indicating that you are definitely pregnant. From now on your body is going to launch a global hormonal rearrangement. Spotting during implantation doesn’t have any impact on pregnancy itself.

The problem is that women often take pathological vaginal discharge with blood for implantation bleeding. You must be alarmed if your discharge is accompanied by strong lower abdominal pain, severe nausea, sudden vomiting and dizziness. These can be the symptoms of ectopic pregnancy or miscarriage. Such conditions require urgent medical help.

  • Character of the bloody discharge.

We know that implantation bleeding looks like spotting. At the same time period usually starts from the similar scanty discharge with blood that is intensifying during the next few days. In rare cases implantation bleeding occurs shortly before period or even during period. In this case you should pay attention to the character of your discharge. If it is slight and do not intensify, it can be the sign of successful conception and implantation.

  • Additional testing.

If you notice the typical bloody discharge you may make a pregnancy test. It can be already taken on the 8th–10th day after ovulation. However, do not expect the brilliant accuracy. If your hCG-level is not enough yet, the home pregnancy test will show you the false negative result. Try again later, better in a week or two.
