ANYONE WHO CAN HELP ME UNDERSTAND WHATS HAPPENING PLZ...

:? My husband and I have been ttc for over 8mnths now with no luck I have the CBFM & I used over 400 Ovulation tests but I never seem to be ovulationg but anyways back to what I was talking about... On Saturday of last weekend I noticed spotting in my panties and only a little on the toilet paper so I cleaned up and put a panty liner on but there wasnt anything but little spots on it I did have slight lower abdomen pain not like normal cramping but since then I've been spotting or slightly bleeding its not enough to be a period I am due for my period on the 11th of this month what could be going on... I can be email or messaged back on here I'm just new to whole TTC
