I usually ovulate on the 17th day of my cycle. Usually the OPKs are negative until day 17, then I get my positive, then on day 18 its back to negative. My mucus usually is ewcm on day 17 as well. This cycle my mucus has been all over the place. I will have ewcm then be completely dry the next day. My question is that I did get my OPK positive on day 17 (but had no mucus), then got a positive OPK again today (day 18) and I have ewcm.....So which day should I consider my OV day? I am supposed to get a progesterone test on 7dpo and then estrogen at 10dpo so am trying to figure the days out. Thank you for any advice!
