I have very irregular periods anything from 34 - 60 days is normal for me. On sunday night (cd43) I felt crampy and realised my period had started, i'd had achy boobs all week too. By tuesday morning it had stopped, nothing all day then this afternoon i've had some light red/brown bleeding. My boobs are still tender and a pg test shows neg. We have been having unprotected sex for a year now but don't hold out much hope as dp only manages to finished the job occasionally and only has 1 testical. Any ideas?
