Pregnant 🤰🏼

Me and my partner have just found out we're pregnant! 4 weeks yesterday. I'm so happy but I can't help to hide my excitement as I'm so scared to get my hopes up as anything could happen as we're so early in. Everytime I go to the toilet I'm scared of bleeding and misscarryin. Is this normal 😭 I've booked a private scan for when I'm almost 8 weeks as I just need reassurance everything is OK and there is a heart heat
