Are these REAL?? HELP!

Ftm- I was dilated 3-4cm Wednesday evening and sent home to labor down. Contractions haven’t stopped being consistent but felt more like BH. It’s 4:20am. Friday and I’m having something different. Starts at top of fundus and sends a shock feeling to my vagina and leaves me cramping until the next one about 5 mins apart. My vagina hurts SO bad too. Is this go time? I don’t want to miss my epidural window.
