im 18 and ive been pregnant once before but miscarried. i missed my period three days ago and yesterday i started spotting and had major pain in my lower area. i didn't bleed like my period it was pinkish and light. my pain in my lower area was on and off and was very bad. i have never had a period like that. my stomach feels hard too. ever since i missed my period i have woken up feeling like im going to throw up. ive also felt sick during the day. i am or will be 4 weeks prego on Saturday if i am. im not sure if i am prego. ive had light pains today in my lower area. i don't know if i am pregnant or what. i feel pregnant and i need help. is it too early to take a pregnancy test? i took one at 3 weeks and it came out negative but i guess it was too early. also ive been wearing a pad and my blood flow hasn't been the same as it would if i was on my period and im a b***h when im on my period and ive been totally fine nothing bothers me. i don't know my boobs don't hurt when i touch them, they haven't changed colors. what should i do?
