Help please TMI

Melanie
So today im 6 weeks 3 days. I woke up with sharp pain on my left side right next to vagina. I went to the bathroom and when i peed there was brown blood when i wiped. No clots not heavy more like spotting. I asked my SO if we should go to e.r he said if it gets worse yes so we went back to sleep for another 2 hours when i woke up to to pee again no blood but now like a sore feeling in my ass... I have been costipated for a few days now. & finally went a little bit today.... Anyone else experience this or should i go to e.r ?
