I am a 23 old female. I was diagnosed with hirsutism 2 years ago and was prescribed krimson 35. And was asked to take it with a gap of 1 or 2 month. I had not taken it for about 2 months. My last period came on 5 nov. I had sex (protected) on 17 dec and took an ipill the same day. Now I am 11 days late for my periods. Took several preganews tests that came out negative. Took a beta hcg test that said hcg below 1.2.why am I still not getting my periods? I am really worried. Is it sure that I am not pregnant? I don't want to be. Please help.
