With this pregnancy, I didn't notice ANY symptoms at first. I think I was close to 3 months when I started getting the sore breasts, tiredness and all that.

However, with my first pregnancy, between 1 and 2 weeks after conception I had an extreme unexplained emotional swing; became very tearful for no apparent reason. This didn't last longer than a day, and I couldn't work out the cause of it. When I found out I was pregnant, it was a relief to realise it was probably the hormonal flow causing this emotional upheaval.
