I am now into the 24th week of my pregnancy. While things have gone very smoothly thus far, I had quite an alarming rash break out on my belly on two occassions last week. In both cases the rash - small red spots with no itiching or irritation of any kind - appeared in the evening at the end of a long and fairly tiring day. The spots were gone in the morning. Is this something that happens around this time? I'd much appreciate any advice on the subject.
