Hi,
In my first pregnancy I became very itchy early on, like you. In the morning I would be basically fine, then as the day went by I got these lesions like hives in the "hot spots" of my body. Like under my arms, on my neck, in the small of my back, in my inner thighs, behind my knees, etc. By the end of the day it was terrible! My OB didn't know what it was because it isn't uncommon to be ithcy during pregnancy. After many consults with varying doctors, I was diagnosed with PUPP. Look it up online if this sounds like you. There is no real cure for it unfortunately, except certain creams that are safe to take when you are pregnant. It went away about two months after the baby was born. It was hard...really hard! I found others online who had it and found comfort in getting their advice and support on discussion boards. I hope this isn't your fate, but if it is just know that it goes away and you are not alone. I think 1 in 1,000 people get it or something like that. Best of luck to you!
Debbie
