I am 25 weeks and had a rare act of "morning sex" a couple of days ago (I am more of a night person). I then had to deal with very strong Braxton Hicks contractions for most of the day. I was cramping and my tummy was going so tight. It freaked me out at first, but after a bit of research on the net I realised that it was pretty normal to get BH's at this stage in my pregnancy and that the more pregnancy's you have had the stronger they get. Seeing as this is my fourth pg, I am expecting more BH to come.
