Hey ladies!

So this is our first month ttc, and my first cycle off of the pill. I have no idea when I'll ovulate but have been crampy this last week and waiting for ewcm. I finally got the ewcm tonight on what I believe is cd 13 (not sure if I count from last active pill or first day of bleed). Well, my SO is out of commission tonight, so I'm wondering if I'll still have a good chance if we wait until tomorrow night. Any help would be awesome on ttc, especially with tracking cm (how long does ewcm last before ovulation etc.) This is my first time trying and I'm so excited that I'm turning into a crazy lady about it lol. Thanks in advance!
