You are to early for a strong heartbeat it will pick up in the weeks to come so don't worry you are still early to tell I did the same thing
My baby at 6 weeks had a heart beat of only 60 something. They said a baby's heart beat should be in the high hundreds. I was trying to prepare myself for a miscarriage. He's now 19 months. It took a little while for his heart to start beating faster but he fought through it. He's healthy, he went full term. Hope this eases you a little. It's not up to a dr it's up to God. Keep me posted.
He didn't say what the rate was
