scared and confused

Lacey • My name is Lacey, and I’m a mother to a beautiful baby girl. We lost her father in march, but we're ready to push forward with my sweet partner and our new life together. ❤️❤️❤️
I found out yesterday that I'm pregnant but very very early (estimated between 1-3 weeks) and the doctors frightened me. I went to the wrong last night because I was cramping and had a little pink on the toilet paper. When I got to the doctor, I had like period spotting for about an hour but it wasn't heavy. And it stopped and so did the cramping. I'm haven't cramped since, but they said because of the bleeding and my past molar pregnancy my whole pregnancy will be high risk. They said as of right now because of the spotting that they're gonna say that's it's a threatened miscarriage. Should I be concerned? I'm seriously scared for me and my child. Any advice or personal story would help. Thank you so much.
