I have been trying to conceive. I had intercourese before and on the date of my ovulation and fertile days.About 10 days later I started bleeding light then heavy.For about 4 days.It was 10 days after ovulation and two weeks early from my normal menstrual period.The questions are:could that be implantation bleeding? Could i be pregnant?

### output:

Hallow Dear, I have gone through your history. I feel there is some confusion in calculating the days of ovulation and fertile period. Ovulation takes place 14 days prior to next expected menses. The egg has life of 24 hours while the sperms are active for 72 hours. Hence, the fertile period is a period of one week around the days of ovulation. Since the ovulation takes place 14 days prior to next menstrual period, your bout of bleeding cannot be 10 days after ovulation and two weeks before expected date of period. This statement suggests that you are having some misunderstanding about ovulation day and fertile period. Whether it was an implantation bleeding or it was Mittelschmerz (ovulation bleeding) can be decided only on confirmation of the pregnancy. You may take pregnancy test on the overnight first morning urine sample 8-10 days after missed period; done earlier these tests may give false negative results. Alternatively you may opt for Beta Chat Doctor test which is very sensitive and can give you reliable results even few days before missing period.  Since you had considerable bout of bleeding, I would advise you to go for ultrasonography after 10 days of missed period (in case pregnancy test is positive) to assess the safety of the baby. It will inform you whether the bout of bleeding has disturbed the pregnancy or not. This will resolve your dilemma.
