My nausea in my last pregnancy only lasted a few weeks then never came back! I'm the same as you now, 7 weeks and I've been generally nauseous for a week. No better, no worse!
Mine started at 5 weeks but has let up now at 8 weeks. I only feel a little nausea every once in a while, nothing bad but still annoying. Hope yours gets better fast!
The first time around, it got worse. Started out gagging, then went to dry heaving, then threw up once and then threw up every 15 minutes for an entire day before I finally broke down and started taking Zofran. This time, I started out with diclegis and I'm hoping it stays manageable.
Re: Will the nausea get worse?
Gotten worse (but not terrible). Everyone is different though.
