Thankyou everyone for your replies. I'm sure it wasnt my surgery from the ectopic pregnancy playing havoc on my period as I had that back in June and after that went straight back to my normal cycle. To be honest I think its a mix of TTC anxiety, last months chem pregnancy and maybe even the fact that I am getting my hopes up and stressing myself out. 2010 is a new year and I will be calm, calm, calm & will try to not even think about baby making
