Do antibiotics affect cm? I had my wisdom teeth cut out 5 days ago and have been on antibiotics for about a week... The cm is finally chilling out a little... But it was crazy!! Stretchy and basically falling out if me!! Gross I know, but it was happening!! Because of the pain I have been in we only managed to bd once.... But I was wondering if maybe the meds had given me fertile cm.... It was certainly increased! Haha and it was right around my normal ov time.... But I have also heard that meds can delay ov... Any insight?! Thanks!!
