hi, me and my husband are currently ttc. we have been having unprotected sex all the time in the month of november. he has came inside quite a lot and i got my period so i dont think im pregnant. although, i have been having trouble breathing and i heard that its common in early pregnancies. also, ive been using the bathroom a lot! i went pee about 3-4 times in a 30 minute period. anyways, something about this period doesnt seem right.. its really heavy and i only have cramps on one side? they arent really bad cramps either! we want to be pregnant... what can we do ? or could we be pregnant? i heard that some women get their periods in the first trimester! also, could being on birth control for 3 years & being off of it for 4 months play a role?
