5 weeks and 4 days pregnant-nothing in ultrasound

PJ • TTC since August 2017 for baby #1 🤵👰 September 2017 Pregnant with baby #1🤰 #endometriosis #septateuterus #adenomyosis

I had cramps so, went to urgent care. When they did ultrasound, they didnt see anything. I'm worried. I need to go for another viability ultrasound in 7 to 10 days. No spotting or bleeding. They made sure nothing is implanted in my tubes. Please help!
