Baby measuring behind

Hey there! I am currently 7.5 weeks pregnant.. my first ultrasound was vaginally at 5 weeks 4 days due to some pain, and all ways measuring normal- the sac was seen in the right location. Next ultrasound was vaginally at 7 weeks on the dot, and I was measuring 6 weeks, fetal pole was detected and heartbeat could be seen, not heard. Today I am 7.5 weeks and had a belly ultrasound and am still measuring 6 weeks, still have a heartbeat... I was wondering if anyone has ever been in the same boat and what the outcome was? Thank you!
