Suggestions Welcome!

Last Thursday I was eating some steam Shrimp (Chewing slowly) and afterwards it felt as if one did not go down.

Since then I feel like something is still in my chest.  I am able to eat and drink but it's just a nagging feeling when I am sitting or standing.  Does not bother me when I am laying down. 

I am about 11 weeks out.  My next doctor appointment is on the 7th.  What should I do?

You can always call your Dr before the 7th and ask, but I think it's more likely gas. If it was well chewed then I cannot imagine it not going down by now. I mean your stomach acid would have turned it to mush by now.
