Good day, my girlfriend took cytotec to abort a 4weeks pregnancy. She believed it went successfully as she saw the sac. A month after, she saw her period. But since the month she saw it,she hasn't seen her period. She is 2 weeks late. She did 3 home tests and they all gave negative. We haven't has unprotected sex. She is worried

First, even protection fails, I will assume condoms, which has a 3 to 16 percent failure rate.

So, if you are having sex, then of course, she could be pregnant. And some times at two week late a false negative is possible.

But also this could be a result of the medication

She really should have had a follow up exam after the use of cytotec to confirm her results. The lack of a period now may be due to the cytotec, but since it has been over a month, and she has already had one period, it would be wise for her to see her doctor.
