This is our first month TTC (well we had a practice run last month but given it was my first AF for 2.5 years it was a bit half-hearted/unknown) and I am trying to monitor my cycles but:
- had EWCM from CD10-17
- no positive OPK - tested once a day from CD9 (usually in the evening but at the weekend I did it in the afternoon)
- temps have been fluctuating, had 3 rises on CD13-15 but now back down again but using DS's digital thermometer and range is only 1 decimal point plus if I take my temp 3 times I get up to 4 decimal point range over the course of a minute so not sure how accurate it is. I have just bought a proper BBT for next cycle
- had sharp pains in right side of abdomen on CD13 and pains lower down on CD17
I'm using FF but it can't determine anything yet. 
So, what do you think? How likely is it that I have OV-ed this month?
