I thought I was pregnant but never did a test but was feeling sick and lightheaded but my sister is 16 weeks pregnant and I shrugged it off thinking it was nothing. A couple of weeks ago I started cramping then I had spotting and a brownish dark discharge I thought it was because I was on a new contraceptive pill and hadn't had a period in a few months but was watching tv today and they were talking about miscarriage and then it hit me that I may have had a miscarriage. I don't know what to do now? I'm going to go to the doctors but I haven't told anyone not even my partner! Please can someone give me advice?
