Hi as my fertility window is approaching and this is my first proper month ttc (didnt bd until after o last time but didnt realise it at the time). I keep getting negatives on the o tests but there are 2 lines so im hoping i will get a positive in the next couple of days. Just wondering how often we should bd to maximise our chances? Everyday or is every other day better does that make the sperm concentration better!? I havnt got a clue
