Six week pregnant cramps


I am a little over six weeks pregnant I found out on July 27th with a positive digital test. I suspected I was pregnant about a week and half before I took a test but was in a bit of denial. All first symptoms were pretty familiar as I have been pregnant before and miscarried the swollen and almost prickly feeling in my boobs and nausea. I also both times got this sharp pain in my left side the only difference this time is I’m having pelvic cramps or pain randomly that starts sharp and becomes dull and it almost takes my breath away and I have to hunch over and then it’s gone. It happens randomly sometimes a few times a day sometimes once a day there’s no real method to it. I also noticed when I orgasm I get that pain or when I’m trying to go poop I get that pain is this normal ? Should I be feeling concerned ?
