I had sex with my husband about 4 days after my period ended. 2 days later, I took the plan b pill (the one dose kind). 3 days later after taking plan b, I started bleeding. I considered that my period starting again? I went on birth control that day (considering it is my first day of period). Had sex the day after I went on the birth control pill. Could I be pregnant?

I took 2 home pregnancy tests (although, it's only 11 days after sex), and they're negative.

Typically there will be some bleeding when taking the Plan B. It has to be taken within 72 hours of intercourse.

You are not protected on the pill until you have taken it consecutively for 30 days (on average depending on the pill.)

It would be too early for you to take a test if the intercourse was only 11 days ago. It's best to wait until your period is due, or you miss a period, to take a test using first morning urine.

They could still be negative if you have a regular cycle or positive if you have a 26day cycle or less. In other words, there are many possibilities you could still test negative a week after or a chance of being pregnant.

Yes you would get the negative reading only 11 days after sex.

You should have some bleeding from the morning after pill, so that would not be your period and why did you think that was your period, if it was only about ? Two weeks after your last period if I sort of add the sex, and pill and so on up.

But the other issue is that the morning after pill will also going to mess up your period for a month or two.

You will have to wait for about 2 weeks to do another test.
