I have bad light reddish and brown spotting for 3 days now. I have had unprotected sex 3 weeks ago and I know he pulled out before he did his thing. And I haven’t had spotting for 3 months and then it appeared. Is this a sign of just my birth control or am I pregnant? Would there be other signs if I was pregnant? Has anyone else had this problem? Please help me! I’ve been stressed the last 2 weeks and exercising could that be it? I also have never missed a pill or took it at the wrong time? I’ve been on extended cycle birth control pills for 8 months now. Is this normal? I’m suppose to get my period in March.... since I get my period every 3 months.
