I am using a contraceptive pill for almost 6months,then we decided to stop it because we want to have a new baby,so I stop the pill last April 10,2011 then April 15,2011 I have an menstrual period in 5 days after that,after that after 4days we had an intercourse.this month of MAY me and my husband had an intercourse for several times already. Then may 5 I had an menstrual period.what happen? I should be pregnant right?

Is this in the math-science forum because you're attempting to multiply?

EDIT: By the way, this post was originally in the homework-help/math-science forum before one of the admins moved it to this more appropriate home. I swear I'm not entirely crazy. :)

In all seriousness, even under ideal conditions couples often try for years to get pregnant. Expecting to get pregnant within 25 days of getting off the pill seems pretty unrealistic to me.

No, you don't automatically get pregnant when you stop taking the Pill. Your body has to adjust your hormone level. It took me THREE years to get pregnant after stopping the Pill.

So it is taking a little longer to get pregnant that you had anticipated. Maybe it is because the pills have an after effect and it takes a little while longer for that to wear off even though you have stopped taking them completely. Also, you don't get pregnant EVERY time, maybe it is just taking a little longer naturally? Regardless, enjoy the baby making process? ;)

Good Luck,
