hiya i usually have a 25 day cycle. Last month my cycle was 30 days. I thiink this was because in august i took the pill so that i would not have a period whilst i was on holiday.After my holiday my period came on 08 Sept and lasted until 13 Sept. I estimated my period to be due on 08 Oct with my usual 25 day cycle. I have not yet had my period and i have been very sexullay active after my period so i am quite sure that i have had sex during my fertile time. Last week i got the usual symptoms of coming on my period but they have been a bit more intense than usual and right now i have lower back pain (which i never get when i am coming on my period) i feel very bloated, my breasts are sore and i have been suffering with dizzy spells. Does anyone have any suggestions for me my periods are very regular and do usually come around the 7, 8, 9 of the month. Am i being paranoid about the whole situation or is there a chance that i could be pregnant? Please help thank you
