Once you start having O symptoms how quickly does your Oday approach. For example, yesterday was CD13 and I had O symptoms. Those symptoms increased today. Do you think I'm Ovulating today or tomorrow or even the next day? I guess my question I'm trying to ask is once you see symptoms when do u count your O day (the next day u will O or maybe it's 2 days after symptoms start?)? Uggh! Hope that makes sense?? Im not using OPKs because I heard people with PCOS are waiting their $$ buying those b/c they might not be accurate. My symptoms right now are lots of mucous, high soft open cervix, maybe a little cramping.
