Thoughts? Help?

I’ve felt off and nauseous all day despite taking my max Zofran dose every 8 hours so I tried to lay down and rest. I just projectile vomited all over out of no where and it was a ton. Hubby helped me get in the shower and after washing up, I went to dry off my vagina and there was brownish discharge that I’ve never quite seen before? I wiped a few more times with different spots of the towel and it was still there but lighter. I’m so confused because I had literally JUST washed and rinsed it minutes before wiping with the towel.

I had felt damp after throwing up but just assumed I may have peed without knowing it? I’m not feeling contractions, just a lot of tailbone/pelvic pressure and some lower back pain. I’m 36 weeks and 90% effaced as of my cervix exam last Tuesday but hadn’t dilated yet. It’s just so weird? I’m going to lay down and pay attention to any contractions but, as a FTM, any thoughts? Is it particularly bad to have that color discharge suddenly? Feeling more period like cramps as I type this but nothing I can quite time just yet. Ugh.
