Still not pregnant. Period started..feeling bummed

So my period started today. I really was thinking this would be my time. Everything was perfect my follicles were good I took my ovidrel did my day 21 progesterone an results showed I ovulated and still I didn't get pregnant. Any words of encouragement or input. I had one miscarriage and serveral rounds of letrozole this was my 2nd round with ovidrel.
