Burning in pelvic area?

Kristin • Our tiny miracle is due October 23rd.
I am 6wks 1day and I have had a burning sensation a couple of times in my pelvic Area for the past couple of  hours. I am not cramping or anything. Is this normal? My hcg levels were checked on Thursday and came back at 22,000.  I miscarried quadruplets in September after trying for 2 and a half years on a non medicated cycle so I am a little paranoid.
