TMI - feeling heavy/ swollen down there

Lori • Wife, mom x3, 2MC, 🤰#4 & #5 ♥️🇨🇦🐄

I am 30w1d. Had any else been experiencing a heavy/full/ swollen feeling down there? This is my third, and for 2-3 days after sex I am so sore and full/ swollen feeling. We’ve been decreasing the amount we have sex but I just can’t give up lol

I also have terrible vericose veins by my vag, thighs and legs. It could just be the main vag vein being irritated?
