Me and my boyfriend had PROTECTED sex for a couple times in March, we took a bath after but he cleans himself off before we lay down together in the bathtub. my last period was the 21 of February and I am 16 days late now. I had a very tiny little bit of spotting for ONE day only and never happened after that. I have not experienced any pregnancy symptoms other than that little spotting but it was only for one day and a very tiny little bit. My periods are a little irregular. I've been stress out a lot lately because of this, does this cause my period to be missed? Or am I Pregnant? I don't know when to take a Pregnancy test because I dont know if it is still too early to take one. Please Help!
