Ttc after having my son(never had an issue conceiving him) til now. Diagnosed with Pcos and after a year of unsuccessfully getting pregnant my doc put me on clomid (50mg 5pills) Tuesday may 30th went in for ultrasound and had one healthy follicle (size 18+) so here i am cycle day 15 and no ovulation yet , im using clear blue digital oculation test ... Has anyone else used clomid and gotten pregnant?
