Need your wise ladies advice. I've just turned 40 and TTC. I have 2 LO and had a missed M/C in Oct 13 which required a DC. Ever since then I've had irregular short cycles (18-24 days) with spotting. I've never had this prior to my missed miscarriage always 28 days. I've had all the blood tests and U/S and everything is fine. I know I'm ovulating from all the test they put me through. I have been using OPKs to pinpoint BD but not being successful. I have a feeling my luteal phase is too short. Any advice please.
