Hi sorry for long post. So my youngest is 3 me and oh decided after such a traumatic birth and financial reasons etc we did not want any more children I'm 31 he's 39. We have been using natural family planning as contraception and it has worked perfectly for 3 years I use a really good app which tells me when I ovulate and when af is due and its always 100% correct. 11 days ago we got carried away and DTD he pulled out but he's not sure it was on time. When I checked my app it was ovulation day! So af is due on wed and I'm 11dpo I am so so moody like unbelievable and have been for past 3 days I have sickly feeling and few niggles right down in my tummy I don't usually get af symptoms until 2 days before its due and its usually cramps not the other things I'm feeling. I'm absolutely terrified af is not going to show up do you ladies think this sounds like pregnancy?
