I am 18 years old. No kids, have sex quiet a lot but with a condom, had unprotected once about 3-4 weeks ago but took out before he could bust. I'm a week late on my period I was supposed to start september 25, I thought I started my period yesterday but it was dark red heavy bleeding for 24 hours then it turned into light brown discharge going into today and it stopped completely. about 2 weeks ago I was light pink spotting for 2 days. I'm really confused? I haven't tooken a pregnant test because I really didn't have any of the symptoms?
