about a year ago i had the same problem, no period but a neg. pg test so i went to my obgyn and had a blood test dun to check for hcg, it was present so i scheduled another appt to see if it had risen.. it had actually fallen, seeming that my egg was fertilzed but had not implanted. currently.. i have been on birth control but have missed a few times this month, i spotted about a wk before my xpected period for 2 days and then nothing for a period.. i dont feel like i have any symptoms but it may be too early, my home pg test said neg a few days after i was supposed to start.. i am not sure if it didnt come because i messed up pills or because i got pregnant, and a neg test isnt enuf.. shuld i schedule another appt for blood work or wait until next month and see if i start? or take more tests? help!
