Hope I haven't already asked this question but here goes!!! My luteal phase seems to be shortening. Last month it was only 11 days and this month it was only 10, although I'm not sure if FF is being completely accurate with me. Usually after a positive OPK, I ovulate that day or the next but FF is putting it later. Anyway, I'm thinking of maybe taking Vitamin B Complex and Agnus Cactus. My question is can I take this both at the same time, and do I need to stop taking it after ovulation? I just want my regular cycles back. Someone told me that by having a short luteal phase, your body could get pregnant but by the time it starts to happen, my period is already starting to happen which means the pregnancy isn't sticking. I know that my boobs have been hurting a lot more over the last 2 cycles and my periods a lot heavier.
