Well DH and I certainly aren't trying for DC2 but I have a feeling we may have conceived him/her. Had a quick shag on Mon night, I wasn't concerned because I knew I'd had my period while we were on holiday and that was two weeks ago - it wasn't, it was one week ago, it just felt like that long! Some speedy maths showed that we'd shagged exactly 2 weeks after my last period started, slap bang in the middle of my fertile window. Today i spent the afternoon with a hot bottle on my belly because of huge cramps, I also bent over and my boobs ached like crazy. Waaaaaay too early to test but feel pretty certain I'm preg. Anyone else in a similar boat?
