So I used first response opk last month and it should as my gyn said that I ovulate the 21st day of my cycle , day before ov date I got my positive. This month I tested the same way and no surge 😁I still had sex on the days but today another high day per this amp I'm not able to because hubby isn't here 😁 any way I finally used preseed started with full amount then realized I need less but for me it took away pleasure from sex I compared with TTC and I prefer it better so I had two days pressed and two days TTC 😁😁 back to my opk has anyone had this happ? I know I ovulate because I've done all my testing
