I missed my period this month .. my last period was June 12th-15, 2017 .. which means my menstrual cycle is like 30 days .. I had sex on the 27th when I was fertile so now it's about to be a week I missed my period and I really don't think I have any symptoms unless these are some my head hurts every night, my back be killing me I have been constipated twice I know TMI . I don't be feeling like I have to throw up but I do feel sick some times .. what do you think ??🤔🤔 I'm scared I'll be disappointed if I take a test .
