My last period was Feb 2. Me and dh had intercourse on the 19th. He didn't finish in me. Now I still have not had a period but Fri I started spotting and it was kind of browny and then went kind of redish and now nothing. It only lasted like a day and a half. Has this ever happened to anyone and then they found out they were pregnant? I thought of implantation bleeding but I think it is kind of late for that considering that Ishould have had my period before Fri when I started spotting. Any advice would be great!

You can never tell with these things.(I'm guessing you are trying to conceive and there for aren't on any birth control?) It could have been implantation. Or just some spotting, or a short period. Even if he didn't finish off inside you, you could still be pregnant, as pre- has sperm in it. I would wait until you miss your period. Take a test the morning after you miss your period, with first morning urine. If it comes up negative, but you still don't get your period within a week, get a blood test done. Good luck

OK but I am already late for my period. It should have been early March. So therefor I guess I should take a test.

It would be advisable to test using the first urine you pass when you wake up in the morning.
