Have any of you had periods back yet? I know they say periods can take a while to return but already had one. First was 11th Jan, usually 28 days between and was due last week again but not had it. Should I worry? I have had sex maybe 5 times, every one using a condom apart from first time when DH withdrew. I had cramp a few days ago but nothing since, boobs feel fuller and heavy today. Give it till end of the month do you think? TIA x
