hi, i'm a 18 years old and have noticed some blood when i wipe after i am done urinating. it's not much, only once there was more than usual. this is the second day this is happening, and at first there was some brown discharge, but now it is just when i urinate. i put a tampon in to see if there was anything else, and there was some dry, brown blood (which looked like old blood to me) and some red, but it was barely any! i am on junel 24 fe, and had my period on december 28th to the 31st. however, i got it on my second day of the inactive pill, and it stopped when i was back on the inactive pill. i had unprotected sex the 26th, but there was no cum, he didn't finish at all, and it was only for about 2 minutes. i'm not really worried about that, but i am worried as to why there's blood. i am not actually bleeding, i just see it when i urinate. i am on top of my birth control, and i also take levothyroxin for hyperthyroidism. could this be it, or maybe it is old blood, or maybe hormonal imbalance? please help! i'm very concerned
