Ok so I've been trying to concieve for 5 months but the thing is my cycles change every month so far it's been two 31 day cycles then a 30 day cycle then a 29 day cycle then a 28 day cycle what is going on with me? I'm in the 2ww now I have no idea how many dpo I am I'm guessing 9 dpo but could be wrong as I have no idea when my next period will arive anyone have this problem?
