Popping in from 'waiting to try' for some advice... My average cycle is 27 days, soemtimes 26 sometimes 29 latest 30. For a few months I've been getting abdominal pain (personally think it's bowel related, as I've been constipated too) eventually went doctors and am awaiting a scan. Doc asked about my periods (which were regular & normal... This was a week ago Tuesday) and she asked about ovarian problems in my family which scared me. Now to make it worse my period was due Monday and is still not here. However I've had flu & tonsillitis and was on antibiotics for a week. Could this make my period late by messing with ovulation? I'm scared it's something ovary related. I'm getting the feeling of period coming but still no sign.
