Did I miscarry? (Loonnggg Story)

Hi ladies. I had protected sex with my boyfriend of 8 months (we used a condom). The first time was on Wed 8/3 then again on Thurs 8/4. The first time, we used a lubricated condom with spermicide, and the second time, the boy felt like there was too much lubrication, so we tried one of the plain latex ones. It hurt (we didn't check to see if the condom got torn), so we switched back to the other one. We haven't had sex since. I started what i thought was spotting on Sunday, but I later figured out that it was a really heavy period. I did what doctors do not really recommend, which is go on the internet and freak myself out and not go in for an appointment, which would be really hard to do because i am a 14 year old living with my overprotective mother who would never forgive this. On the internet, i found a lot of stuff about possibly miscarrying, vaginal trauma, STI warnings. We used condoms both times but it was in bed and i believe it's possible some of his fluids got inside me. Do any of you ladies have and idea or have experience with this?
