Is their a chance I might get pregnant?

[Lez2000]

So on Feb 8th, I had sex with my boyfriend for the first time and we used a condom at first but we got frustrated. So I just finished him off with a blowjob and we layed down for a few minutes, I told him if he wanted to try without a condom. He said sure and we didn’t use a condom this time but he pulled out. After we got so scared and drove to Walgreens, bought plan b, took it when I got home. We waited and I have a predictable chart where it says I wasn’t “fertile” and that my ovulation was on “Feb 11th”. So now I got my period today, I noticed that it was red and brown, so I went to update my chart and it said I was fertile on the day we first had sex! Apparently I was at 33% risk of being pregnant, I was freaking out because yesterday, which was feb 22nd I had sex with my boyfriend again, at first with a condom, he came and second, we didn’t but he pulled out. So I’m freaking out (I know that Precum contains some sperm) but I know it’s 14 days before your period that you ovulate. But I had my period today, I threw up but I was thinking that maybe because of the heat, since I have been out since 6 in the morning. In this florida heat, I threw up the water I was drinking. I’m really stressing out and I need some help or advice. (Also my parents are very strict and don’t want me having a boyfriend, especially not having sex. I asked my mom if I can go on birth control and she told me why? And that I have to be with someone first. So I was so scared to tell her cause she would have been so mad and would have told my father, who has bad anger issues. I fear the worst...)

Okay, glad you used a condom the first time!  But do that EVERY time.  Because as he may have pulled out, he still had an unprotected penis in you that will emit a small amount of sperm.  That's enough to get pregnant.  You took Plan B though and that will make you irregular.  You could spot, not have a regular period, be super late, etc.  Plan B works by introducing a big dose of hormones into your system.  This is great for preventing pregnancy but those hormones also mess up your system/cycle.  Most women are irregular for the next 2 to 3 months.  Make sure to use good birth control because you don't know when you'll next ovulate.  good luck
