on the 30th i took out my birth control (nuvaring) and had unprotected sex about every night with him pulling out, from my understanding you cant get pregnant right before your period.  on the 5th i started my period and it ended on the 9th. Same as every month, my periods and very regular. on the 12th i started getting some headaches, thought i was just dehydrated so i started drinking more water. on the 13th i woke up with bright pink spotting and cramps. spotting turned brown by the end of the day and had a headache all day. on the 14th headache and cramping but the spotting had seemed to stop. tired and a little sick feeling, when i went to eat dinner i had to do it slowly and couldnt finish everything because i kept feeling nauseous.  tried getting a hold of 2 of my doctors and nothing back. my boyfriend was getting nervous so he had me buy a pregnancy test which i took this morning the 15th and it came back negative (not sure if it is too soon to tell). started spotting again brown in color, cramps and headache. Ive never had this before, been on nuvaring for 6 years and never had a problem. no clue what this is from and cant seem to get any answers. Please help!!
