Hi, I'm 22yrs old. Almost 3months ago, I had conception with my boyfriend during fertility without protection, but I took emergency contraceptive.. And ever since, my breasts got bigger by 2inch, I always feel nauseous, dizzy, constipated, diarrhea, my nipples are more sensitive, heart beat are fast and strong, I'm always tired, my abdomen and pelvic hurts sometimes.. But I never missed my period, they all came on time but lasted for 2-3 days only with spotting for next 4 days.. I also took pregnancy tests since my 6th week, all 4 PTs came negative!! All were negative! What could be happening to me? Please I need answer :( I might take abortion pills without confirmation, because I really really don't want to be pregnant. Will I get bad effect?
