Clomid 100 mg

I’m on cycle day 28 of taking Clomid 100mg days 5-9. I took the opk and showed I started to get highs around CD 17-19, my 21 day blood work showed I didn’t ovulate, but I kind of expected that because I ovulated late. Now, 10 days sense, I have been so tired, my boobs hurt, I keep having off and on cramps (not like period cramps, it’s only on one side, and comes and goes, almost like pinching).

I’m trying so hard not to symptom spot, but when do you think would be a good day to test for a possible early positive?
