Okay ladies gearing up and a ?

I went to my OB Monday because we’ve been TTC for a year and he had me in a for HSG rest to make sure there were no blockages. There aren’t! I told him I have a 28-30 day cycle and that I get a positive opk on the 12/13 day usually. He thinks I O later around day 16... he said BD days 14, 16, and 18, but I’m thinking of 12, 14, 16. One issue is hubby has delayed ejaculation so it doesn’t always work when we want it to.

So I’m wondering what you guys think? Any ideas/tips, or thoughts on timing?

Thank you 😊
