Sorry about the lack of a 19 week update, basically had a major lack of motivation, and tiredness seemed to get worse!
So I'm still tired, still got heartburn and still get the odd time I feel sick. I've had quite a bit of backache, which I think may have actually been down to sweeping and mopping at work twice in one week. I also had a day where I felt really achy down below (TMI I know!), and this happened to happen on a day I worked 7am - 5pm. Have also had a bit of constipation. Oh the joys of being pregnant. But the best thing is gradually feeling more movement, and I finally seemed to have popped as well.
