Im 21 and think I might be pregnant. I got my period 2 months ago and it was normail. Then last month i skipped my period and just kept taking my birth control instead of the sugar pills. I got the normal cramping, but this month I have yet to get my period. I have the normal cramping and breaking out but I also feel like I constantly have air in my stomach. I havent taken a test yet honestly cause Im too scared. Should I be worried?
