i had MS with all my children, 3 girls and 1 boy. it was just at different intensities re: sex. my first two girls, had ms all day, every day, no vomiting, but consistent nausea. with my son, it came in waves. i'd feel absolutely fine, then running for the bathroom (DID vomit with him), but once it was done i felt 100% fine again. with this LO...my "wild card" I would have guessed her to be a boy b/c her MS was so mild, and also came in waves like my sons did, although i never actually vomited (like with my dd's)...still it was so mild i thought for sure another boy, NOPE! a girl! surprised all of us! MS is no longer a good indicator for me personally lol.
