Advice

Hello, this is my first post on here. My LH and I are TTC #1. I got off of birth control in Dec. I had AF and then in both January and February I had 21 day cycles on the spot. This past month I started using OPKs. I used CB and received 7 days of 'high' fertility around CD 14-21, but never a peak. We bd 5 times throughout those days, but not sure if or when I ovulated. On CD 22 and 23 and 29 I took HPT and got BFN. Today is CD 30. Since Saturday I have had quite a bit of creamy or watery stringy CM, I have been tired, gas, pressure on abdomen, and a few cases of naseaua. Yesterday I took two OPK. Have been consistently having dark lines with Wondfo, but showed the O with CB. With only being off bc for a few months, is this just AF being cruel?
