Scared with rainbow!

So I'm currently 6 weeks 2 days pregnant. I had a scan at 5 weeks 6 days and I couldn't really see much (but I don't know what I'm meant to be able to see that early...)

Anyways I'm so scared I'm going to lose my baby! I sneezed earlier and had a sharp pain in my side and thought that was it... I'm constantly scared incase I'm bleeding.

I have another scan a week on Monday but I'm going out of my mind incase it hasn't grown any ect. I just want to know my baby is okay!

I lost my last baby at 22 weeks (they think he died around 20 weeks) I'm going to be scared this entire pregnancy! What can I do😔😔
