Rectal pressure/sick?

Kierra • 25 mama to 2 boys

I’m 34 and 2 and all day today I have been feeling super nauseous. Plus I have had a ton of pressure on my rectum (tmi) which is making me have wicked diarrhea. I think I might be sick? Is there anything I could take to make me feel better? I don’t even know what I could be sick with honestly. I’m so frustrated. As if being 34 weeks pregnant wasn’t uncomfortable enough let’s add being super sick to the equation😩 ugh. Any advice?
