Re: Shortness of breath - at end of first trimester...
Hmm... could be a lot of different reasons for it - some benign and passing, but some serious. Definitely worth a mention to your care provider at your next appt, or worth going in right away if it gets any worse.
I think lots of moms get SOB once the uterus starts pushing way up there, that's normal. Personally, I get SOB (pregnant or not) when my platelets drop - SOB and dizziness are my most obvious symptoms.
