Morning sickness starting at 16 wks?

Misty

I was somewhat nauseated in the beginning. Other than that, nothing. Same with my first pregnancy. I'll be 17 weeks tomorrow. I woke up during the night starving so I ate roman noodles and fell asleep on the couch, when I woke up I've felt so sick to my stomach. I'm not keeping water down at the moment.

Yesterday I took my son (almost 2) to a bounce zone, I went up and down slides with him and crawled through bounce houses. My legs are sore, but I can't understand why I'm so sick. Did I overdo it or can morning sickness be catching up with me
