PMS or 5 day pregnancy signs?! ( I am kinda freaking out O_O )

Ok, so I am a bit worried about this. My boyfriend and I were messing around on friday, (note we are virgins.) we did not have intercourse, we were just fooling around, he said that he thinks he saw a drop or so of something that looked like pre-cum, although he said it felt a bit more liquidy/watery then pre-cum. (He said it may have been urine -.- lol, I would prefer that oddly enough) he said he went no where near the vaginal opening, but he said it might have gotten on my clitoral area. Things that are important:

• he went to urinate multiple times before hand.
• he never ejaculated, not before, not after.
• I am on Birth Control, have been for a month and a half.
• I am consistent with taking my pill every day.
• we went swimming a little while afterwards, (There was new chlorine in the pool)
• The only thing that went inside of me, his fingers.(tmi, sorry.)
• he cleaned the drop off of himself when he saw it, he stopped what he was doing., He also used his left thumb to do so, and when he was fingering me, he used his right index/middle finger.
• This all happened on friday.
• I have to wait about another week and a half roughly before I get my period. I have been noticing that I have a little bit of stomach cramping, and my breasts are a tiny tiny tiny bit sore, but that might be from the pill. I have also been extremely stressed out. everyone who I have asked/told about this, have all said I will be fine, as long as I keep taking my BCP, which I have been. Please help. What do you think? Do you think I will be just fine, and that I am being totally paranoid? Thanks.
