So about two months ago I started taking birth control pills. About three weeks into my first pack I was getting really sick so a different OB/GYN switched me to another pill, told me to overlap the two for a few days, then proceed with the new pills. During that time I also bleed the second and third week of the first pill pack into my first week of my new pill pack. Since the change I've been feeling ok, except in the last week or so I've had the following symptoms: nausea/vomiting, higher temperature, food aversions/cravings, I'm retaining fluids in my feet, and my period is a week late. But none of the tests I've taken have been positive. In between the pill packs and the days following, my boyfriend and I had sex almost daily without any other contraceptives. We have been juggling the idea of stopping my birth control since the first one made me sick, and we knew the possibility of getting pregnant, but I'm not sure if it's the medication or if I'm actually possibly pregnant. I'm confused and anyone's input is welcome (providing it's not rude or condescending).
