Should I get checked? 35 weeks

So Thursday morning me and babe had sex and I had the absolute worst Braxton hicks contractions, I’m assuming it was that because it went away but ever since then I’ve been having the same intense awful pains here and there. Not close together but definitely noticeable since the sex. We’ve had sex again today and I have been up all night, trying to sleep since 12 but couldn’t because of the intense Braxton Hicks ive been having and back pain along with my hips and thighs on fire, especially everytime I move. I was in doggie position at one point and it seemed to help a little bit but All night tonight it’s been feeling like I’ve been peeing myself really slowly. I move and it feels more like I peed myself, I go to the bathroom to pee and my underwear is just wet/damp. It doesn’t smell like pee, if anything it smells “sweet” how people say. (I’m a ftm so I’m not sure...)

But before the sex I noticed discharge with a slight brown color, but didn’t think much of it because I know mucus plugs will come and grow back I’ve been told.

Should I go to hospital just in case? I’m supposed to have an appt every week but I went to my appt last Wednesday and was told my doctor wasn’t there and won’t have another appt for two more weeks.... ridiculous but nothing I can do.. advice please ?
