I'm 10MPP and I've had my periods for 4 months now. They have been really regular but totally different than before I had my son. They had been 35 day cycles, but my OPKS and ovulation have been all over the place... Last month I didn't get a positive until CD 28 and my period came CD 34.... this month, I got a positive OPK on CD 23 and started my period on CD 28... i dont know what's going on!!! I'm taking Vitex and my son is down to nursing only 4 times  day... I see my OB on Thursday and plan to talk to him... I just didn't know if this is something he would prescribe me something for, or if it will work itself out... anyone have experience with this??
