I have always had irregular periods and my doctor put me on birth control for about 9 months now and it has gotten to be more regular, and the past 2wks I've stopped taking it ( me and my husband trying to have a baby) and me and my husband have had unprotected sex, and this past week I have been feeling a little sick in the morning just 2 days and my feet have been getting swollen and my hands and my breasts are a little tender and my face has been getting flushed and warm and I've been tired and gassy more then usual, also I had a period for 3 days normal and it went to light. Could I be pregnant?
