Alright. So my boyfriend and I had sex on June 28th. We used a condom, but we also used petroleum jelly (Vaseline) as a lube. Well now I just found out that Vaseline can break down a condom. He checked for holes in the condom, and he told me he didn't see any. Is it possible that there were tiny holes we couldn't see that were big enough for sperm to get through? I'm worried I could be pregnant. AF is due in 7 days. I've been having to pee way more often, I am either starving or I feel like I'm going to puke (I get nauseous every single day at some point), my sense of smell has changed (I can't really describe what I mean but), I'm having some dull cramps, and my boobs got tingly the other day and that has never happened to me before. Today they are really sore. I'm also extremely tired. Could it be pms or do you all think I sound pregnant?  (Copy and paste from earlier cause no one commented.)
