Want to reassure if you bleed!

Grace
Hi everyone,
I want to reassure you all as I went through hell this weekend! I started bleeding in Friday night I'm 8 weeks and 4 days pregnant! I could t stop crying we rushed to hospital they did tests and scanned me and everything was fine with the baby :)! They explained vessels swell and have a higher blood supply when pregnant! Please be reassured and don't worry if you bleed (I know it's easy to say) but honest it can be natural and everything can be fine! Xxxxx
