Pregnancy after miscarriage

I just need some reassurance about this. I have had 2 healthy pregnancy’s before my miscarriage in November 2018 and my period hasn’t came today so I took a test it’s faint but it’s there and I’m so scared. I want to be happy about this but I keep thinking about the miscarriage and I’m scared it will happen again... I know everyone’s body is different and I know I won’t get answers on here if it’ll be a successful-pregnancy or not but I just needed to let someone know so I know I’m not alone in feeling scared about this...
