So I am 4 months TTC with PCOS. Trying to get my life and cycles on track by losing some weight. Very irregular cycles for instance last month my cycle was 50 days and this month its 35 days. I took by BBC Tuesday and Glow said I was ovulating because my degree was +1 then normal but my Clearblue ovulation test was neg. all month!! Was I ovulating Tuesday? Is that even possible being 2 days before my period? Can you get a false reading on an ovulation test?
