Need a bit of advice!

I am 22 weeks pregnant today. So far, my pregnancy hasn't been too bad. I've experienced morning sickness but not frequently and it's been alright since entering my second trimester. However, some days, I can't find any bit of relief. I have a ball of yuckiness in the back of my throat and no amount of water, tums, or Zofran calms it. The nausea is just too much to bare so instead of naturally throwing up like I did with my first trimester morning sickness, I kind of force myself to. It won't be too much but enough to just rid myself of that horrible feeling. This has only happened probably 5 or so times my entire pregnancy so it's not a serious recurring issue, but I'd still like to know if any other mothers have had to do anything like this during their pregnancies. Also, is this potentially dangerous to the baby? Just need a bit of advice and if anyone would care to share their story, that'd be a great help. As you can tell and have probably guessed, I'm a first time mommy worried of just about everything.

Thank you again, ladies.
