Help please!! 8 week scare

Ashley

I had my first dr appointment yesterday, 8 weeks from first day of missed period. They did a regular ultra sound as well as a vaginal one and couldn't detect a heartbeat. It could be that I'm earlier than thought in the pregnancy. I got blood work done and again on Wednesday. My doctor will call me Thursday with results. If my HGC levels went up then all is well. If they went down, well....

After digesting this I considered I'm only 6 weeks. Here's where I need your input. I tracked my ovulation and on May 24th and 25th I was ovulating. Had sex on the 21st and 25th. Do y'all think I'm more like 6 weeks and that's why there was no heartbeat? Trying to remain hopeful
