So exactly two weeks ago from this morning I had un protected sex in the shower with my boyfriend. I didn't think too much of it because he washed himself and didn't have any cum, and we didn't do it very long at all till he put a condom on. I'm worried because I think I've missed my period, I expected it on Friday. But I've never been good at keeping up with them anyways, and I can't remember if it's been 3 or 4 weeks. The thing that actually made me worry was that a few days ago, I had a lot of discharge that evening. I never have that really. I know that's a sign. If it's been two weeks should I take a Preggo test soon (within the next few days)? Or should do I have to be positive I've missed my period to take one?
