I had sex with an old boyfriend a few days ago. He ejaculated inside all 4 times. Well, long story short, I never had the chance or the cash to buy the morning after pill. I have a very irregular cycle, my periods come and go when they want. I am very anxious these days, I was wondering is there even a possibility that I end up pregnant sense I never have my period? I never know when I ovulate either. *p.s I use to be on the pill to regulate my period, but I stopped it, I kept forgetting them and I was not having any sexual activities.
