AF just came yesterday, the 20th, so I ordered the 40 ovulation/10pregnancy wondfo bundle off amazon for this month. I've never used them before so I'm trying to figure out when to start. My cycle is anywhere from 28-31 days (well this last cycle was 33 but that almost never happens). I think my LP is ~16days. So would starting on CD8-9 be too early? Just to be safe. I've just used CM and the calendar to guess at ovulation in the past and I'd REALLY like to know when it is actually happening this month because my guessing game is not getting me pregnant.
Any input would be appreciated
