Low heart beat

Hello everyone

I had my first scan yesterday 6 week 6 days. Doctor said my baby s heart beat is on lower side. Which is 90 beats. My radiologist is saying he would like to see it for one more week. If it increases its good. Otherwise they will think about the pregnancy. It’s an <a href="https://glowing.com/glow-fertility-program">IVF</a> baby

Has anybody else ever been in my shoes? I m so nervous and nervousness is killing it.
