Hi been ttc 2+ years. Got couple of courses of clomid to take, but if these don't work I'm thinking of going to private fertility clinic. We both have had tests on nhs and I have pcos just fed up of waiting times, and can't deal anymore with neg tests every month. Also I've had scan to look at womb etc and all seems normal, is there further tests to see of there could be problems with Inplantation? As past few months I've ovulated with clomid and an positive I've had implantation pain and spotting but then AF arrives.
