Me and my boyfriend had sex on a Monday, and that Sunday I just started my 3rd pack of pills. I believe he pulled out but is could I be pregnant?? We also had sex last night but I know he pulled out.. I should be starting my period next Tuesday. Iver never missed a pill and usually always take my pill around 9:30pm maybe 1 or 2 hours late but that's all.. My stomach feels all bloated and twitchy and bubbly? I don't know if I just have my self worried or what please help..
