I have a doubt whether I am pregnant or not! last month my period cycle was on 19 march it was normal but this month I faced only spots on 17th april which continued till 18 it's color was brownish. And since 17 I am facing shoulder pain, headache, minor stomach pain and sometimes body aches. So please suggest me. I have gastric problem so I use to have es- omepraz dsr once a day so does this harmful or does it effect from being pregnant?
