So been TTC for 2 years now. AF comes every 26-27 days on average. Hard to track ovulation seem to get positive opks several days in a row. Doc says I'm norm and healthy no issues but having a hard time getting pregnant in my 30's now. I have 4 children already. 3rd month on preseed any advice ladies??. I could really use help. During my fertile window I Bd everyday also leading up to and after just to be safe. No luck. My hopes are fading rapidly as I get closer to high risk.. Please cycle buddy be help to me please...
