Okay, I appreciate this might sound like a weird thing to do but...
One of the most relaxing things I find to do is to lie flat in the bath with no water in it, and have the shower run on me from normal shower height. Usually the water lands on my belly/ chest, and I have it quite hot, and I find it really relaxing. It's not a power shower, but its not bad. And I like to have the water hot enough so that my skin ends up a bit pink, like a lobster 
However, I'm about 8-9 weeks pregnant. How does the hot water effect things? And is the water landing on my belly not a good idea?
