I am using the cheapy OPK strips and am currently on Cd 16.
On Monday, CD 14, we DTD in the morning. In the evening I got my LH surge.
We didn't manage to do it the next day, CD 15 ie yesterday...(tried but did not reach a satisfactory conclusion iykwim) but did it again this morning.
Now am wondering if we did enough, or if we missed the boat last night?
We also did it a few times over the weekend.
What do you think...
