So back in October I had a six month window where I had no periods. Glow counted this as a cycle, lasting 167 days. Since then I've started metformin, and my period have been back for 3 cycles now, at 30 days a cycle. How can i stop this cycle from messing with my projections, as every cycle i have to go in and manually change when my period and ovulation is supposed to come? According to glow, I have 50 day cycles, but it's because of the 167 day cycle. Do I just delete it, or is there a way to take it out of the equation without losing that data?
