Chlamydia, Baby, Boyfriend... Life.

I'm 17, my boyfriend is 19 he has been living in my house for about 3 months now and we have been together for 7 going on 8 shortly, I've been on the pill and for a few days recently I let him do his thing inside... After very few times doing it I asked him to stop because it felt to risky, well I haven't been strict with the pill, I didn't take it right everyone in a while and my mom now knows that, because i also just found I have chlamydia and got the antibiotics for it and taken them, I told my partner and he is in the process of doing the same, now my period only lasted a day and now my mom wants me to take a pregnancy test. I love my SO more than anything I'm just scared. I know that this isn't the life I would want for my kids. Please comment thoughts.
