We dtd 4 days before O so I thought I had a very slim chance of conception occuring. I didn't feel a thing... The whole TWW I had NO indication whatsoever that I there was something going on. It wasn't until 5.5 weeks that I started to get symptoms. Though, with my first pregnancy I had every symptom possible. I just didn't want to say yes it was happening as I didn't want to be let down. Though it is in hindsight that I could put it all down to the pregnancy attaching etc
