Has anyone experienced tenderness in the uterus or cervix. I felt crampy yesterday but still did the BD and when I did I felt sharp pains in those areas. We did the BD again tonight and I felt very achy and sore in my cervix. Do you think this means anything?

I just started on this app a few days ago and just started checking my CM. I am irregular too. Tomorrow will be my first day checking my BBT. Until I get a few weeks/months tracked I had to guess and input my periods as is. That means the app predicted my ovulation date to be yesterday.

Any ideas?
