Very Depressed

Hi. Me and my husband have been trying to have a baby for a few years now I've had a miscarriage and a stillborn. We quit trying for a few years after my stillborn. We have recently started trying for the past 5 months. Just when I thought everything was going great in Nov I ovulated and we tried I have also been on femara for 5 mths due to pcos. I was 5 days late in dec. Now its Jan and I'm on day 18 after my period and still no ovulation. I took a preg test it was negative. Just feel bummed and depressed I guess. Any words of wisdom or anyone else going thru this?
