Okay so I am 15 years old. I "kinda" had sex 2 months ago (wasn't necessarily my idea nor did his penis go all the way in) on January 19th. My period came about 3 days after "intercourse". I was freaking out that my period hadn't come last month (February). But I have irregular periods and have gone Months before another period. Well now it is march 17 and I got my period 2 days ago (March 15). this is kind of close to my period in January but that means I skipped a period. HE WORE A CONDOM! Also my breast are growing but I can't tell if it's because normal adolesent growth or because I'm pregnant. Please help me with advice to see if I'm pregnant or tell me the chances of me being pregnant. If I am pregnant I'm nearly 2 months.
Extra information:
I'm considerably "tiny" I only weigh 97 pounds, am about 5"2' and I'm very healthy
