I bled three days about 2weeks ago thought it was AF it was pretty heavy. I usually have 5-6day cycles. Well my breasts have been heavy and sore and all of a sudden i woke up this morning at 5am terribly nauseated threw up and now im fine... Could i be pregnant? I had a csection 4 in a half months ago 3months premature and we lost our baby, maybe that caused bleeding? Idk whats going on i took 2dollar tests but they said negative? And i thought i was ovulating maybe but waking up at 5am like that? Ugh. Please comment your stories or opinions!!!! I guess i would be 7 weeks tomorrow if im pregnant. But idk how? But this morning was terrible.
