Problem, maybe implantation?

hi, sorry this is pretty wordy, i'm just super confused and want to include every detail so i can get an accurate idea of what's going on

i'll be honest, i have sex an average of twice a year. so this past week is worth two years. bad, i know, considering i'm not a very trampy person. even people like me get caught up. anyway, exactly a week ago i had sex with a guy who ejaculated enough to seep out the rim of the condom and onto the outside of my vagina. i was pretty concerned, because this was about two days before i ovulated so i was still super fertile. i started ovulating monday evening when i noticed the thick discharge, but i also noticed the symptoms i usually feel when i ovulate seemed a bit off, or more drawn out. i felt the ovarian twinge-y feeling throughout the next day, but it wasn't very pronounced. it's embarrassing, but the thing that puzzled me most was that i was not turned on AT ALL. i almost enjoy ovulating because i'm not that turned on otherwise, and usually it's very strong for about 3-4 days. this time i only felt it slightly on thursday. on this day i also had a ridiculous ramen craving and ate so much i could have exploded, then a full meal of mexican food afterwards. i felt a little crampy too. can ovulation symptoms last that long into the week? it's possible i had the whole pregnancy thing in the back of my mind and just imagined it. here's where the carelessness begins. i had sex with a different guy (i know...) last night (friday) and the condom straight-up broke at the tip when he came. it was a pretty large hole too. i woke up this morning to feel mild cramping. my period starts a week from monday, so i looked for implantation blood that could possibly be present if i had, indeed, conceived a week ago. nothing was dripping, so i used a q-tip to be sure. i swabbed a few times, and on only one did i see a tiny droplet of blood. what's the likelihood that i could be experiencing pregnancy symptoms a week after? could any of this possibly be related to last night's sex instead? i'll know in about a week if i miss my period, i just hate waiting, you know? i've been feeling slightly menstrual today, minus the breast soreness. i can't really afford to have a kid right now, any ideas of what to do? i could take the morning after pill to take care of the accident last night, but if i've been pregnant from a week ago it wouldn't do any good and be a waste of money. please respond!

thanks for putting up with this ramble!
