Mixed emotions

I don't really say much on here, but all of you have helped me in some way or another and I'm grateful for that. That being said, I've spent the last week obsessing over symptoms and took a FRER tonight because AF is 2 days late. Pretty sure it's a BFP, but right now I feel so scared. Almost a year ago to the day, I found out I was pregnant and at my first doctor's appointment found out I miscarried. I want to be excited so bad, but instead I'm terrified.
