so im not new to this anymore but im a bit confused with my opks. i just had a d&c; on nov. 8th. on nov. 27th i took a pregnancy test and its still positive. I've read that its possible to still O when you have hcg left in your system but i thought it would be another week or two away. ANYWAY... back to the point. i have been using 3 differnent opks to cross check along with CM and CP. Clearblue advanced says im at peak fertility, meijer brand gave a positive but first response is not giving me a positive. i dont have the most fertile cm right now and im still confused on how to check my cp cuz it feels the same to me no matter what.
