So im 15 and i tried to feel my cervix.. when i put in my finger it is really tight and low and firm. Im on day 38 of my cycle (raged from 24-35 days) ive had light cramping and almost rubber like, milky "dry" discharge. (Sort of smells like blood & metal( Does this mean AF is about to start? I had sex when i was infertile, he used a condom, he pulled out and also didnt finish. Does it sound like im about to start??
