Before I miscarried I used to ovulate in cd17/18 and the last 6 months since my ovulation has been cd25 and then 21 each time. Felt like I'd been totally held to ransom by my body because of the ovulation lateness. I had acupuncture last night and this morning, cd17 I've had a blazing positive opk. So thrilled!! It might be the acupuncture, it might not, but I'm genuinely thrilled that I'm ovulating like I used to!
