I visit a fertility specialist and she did a follicle study and confirmed ovulation on 1st april, my last period was on 16 march...i did a pregnancy test 2-3 days back it came negative, i still dint get my period. I am also taking susten (via insertion) as per doc prescription from 1st april (have been asked to take for 20 days). What should i do? Is my period late because im on susten? Should i stop or continue..please advice..could i be pregnant? I am quite regular with my period and there has never been so much delay
