TMI - nausea coming back?

F
I'm almost 30 weeks and I just threw up. I usually don't (this is the 3rd time this pregnancy). I have been feeling nauseous for a couple of days and my energy is non-existent 😞 I thought it was the weather as it's been raining and depressing but I'm not sure anymore 😭. Of course, throwing up always makes me feel worse now everything is burning and I ended up crying like a baby 🙈
I hope this is not an indication of how things will be the coming weeks. I just want to feel normal for a couple of days. I just recovered from a cold and was hoping to feel better before the 3rd trimester catches up with me.
I guess this is just a rant. I'm feeling sorry for myself.
