Hi. I have severe thyroid problem and offenly I miss my periods. due to thyroid I am over weight. Usually I don't get my periods on time Or I do get after 2 or 3 months.Last time I had protected sex with my bf and I had ipill within 24hrs.  after 7days from that I got bleeding but after that no periods and no bleeding .its been 2 and a half months and now I am getting periods pain and little bleeding.i am worried am I pregnant or it is just normal period?
