Have you looked into temping

I buy the cheapie tests off Amazon and have had no issue with them. Clinical guard brand and I believe it's 50 tests plus 10 pregnancy tests for $12.

Do you have a favorite ovulation test strip or kit? I am going to be testing for ovulation in connection with taking letrozol and progesterone. I'm concerned about being certain about what results I'm getting when looking for the LH surge so that I can communicate accurately with my RE and, obviously, have intercourse at the best times.

I noticed some kits also test estrogen but I'm uncertain that this is desirable when I am taking letrozol earlier in the cycle.
