Implantation Bleeding is when a slight spotting occurs due to fertilization. When does implantation Usually, the egg takes a couple of days to transfer to the uterus to get implanted. In some cases, a tissue may break off from the egg and takes time to make its way out of the body since it is very insignificant in size, it may take about 10 days, generally when the implantation process is at final stage.
A highly specialized tissue called the trophoblast develops and barricades the fertile egg. It attaches the egg to the endometrium and eventually it penetrates the endometrium. Trophoblast interacts with the pregnant woman’s blood vessels, diverting it inside itself. The cavities eventually pumped with maternal blood that turns into blood lakes. The trophoblast surrounding the outer egg is comparatively thin and contains cavities that are attached to the deeper cavities. Majority of the cavities are linked. The cavities on the outer portion interact with the uterine cavity in occasions and leaks blood through it. Thus, it’s a straightforward answer to when does Implantation Bleeding occur.
Commonly, Implantation Bleeding takes place 14 to 30 days after
the date of menstrual cycle, between when the egg is implanted and is connected with endomatrium. The spotting that occurs during this period is slightly darker than menstruation blood; there can also be a little blood clot. Unless there is stomach cramps, backaches or heavy flow of blood, it should not be anything to worry about.
If you are wondering when does implantation bleeding occur and whether before menstrual cycle, the spotting can be confused as a sigh of period. Usually if the woman had unprotected sex or is trying to conceive witnesses light spotting before period, it can mean either she is pregnant or she is having signs of period. It depends on the duration of the spotting. If it lasts for more than 2 days it could be she is menstruating. If the spotting lasts for an hour or 2 days, it could mean she is pregnant. The spotting does not even have to be major. It could be one drop of blood on the underwear or the toilet wipe which the woman may not even notice. However, in some cases spotting for more than 2 days may indicate ectopic pregnancy; this is if the woman is certainly pregnant. The best wait o find out whether the woman is pregnant or not is by a home pregnancy test. Usually they work 6 to 8 days after the day of ovulation. But it is best to take the test after 10 days to avoid false negatives.
So, as a repetition, when does Implantation Bleeding occur? The answer again lies between after ovulation and before menstruation, and some women still would panic that it may be some sort of gynecological complication. It should, however, not be anything to worry about if the blood is light pink to dark brown. It is best advised to see a doctor to know whether it’s just early menstruation or Implantation Bleeding. An hCG test or an early pregnancy ultrasound will clear out any confusions about the status of the uterus and determine whether the woman is fertile or not.
