First ill explain. Ive been on the injection or the implant since I was 15 thats 13 years, so I've never had to deal with AF.... So please god don't laugh if this is silly... This month I had two lots of BFP OPKS! the first lot were on the 26th then the second lot on the 2nd! Very kindly I was told its because you can have a surge but not ovulate the first time.... So because I Od later does that mean AF will arrive later? Or will she come at the same time is if it was a normal 28 cycle? Im trying to work out when il be late... If it's the first lot I'm due in 4 days if its the second its about 8 days away Again.... Sorry lol!
