Yeast infection or just sore?

I’m 37 + 2 and had sex for the first time in a week last night night and now my vagina feels kinda raw, itchy and sore and I’m worried it may be a yeast infection.. at the beginning of my pregnancy I got like 4 yeast infections in a row so I feel like I remember them starting like this but not sure. Is anyone else feeling really raw and sore after sex at this late in their pregnancy?

Side note: I’m not having yeast infection discharge and there is no odor either so that’s why I’m wondering if it’s just from sex
