Severe cramps

Bailey • First baby! Learning along. 👶🏼
A little back story: I'm 5 weeks pregnancy and this is my first pregnancy.
Around 3:25 pm this afternoon I woke up from a nap and went to the restroom. Then on the way back to the couch my abdomen cramped so severely I dropped to my hands and knees. I was stuck in this position for a good, half-hour before it was even bearable to get up and walk to that car so my husband could take me to the hospital. They did a UA and US all came back normality the exception of an acute case of vaginitis. No blood everything looked good. Doctor says it was perfectly normal and the cramping was either a side effect of the vaginitis or just the baby getting good and settled in there. SCARY, SCARY, SCARY! I was so worried I would miscarry....
