I had some bleeding at the start of my pregnancy, I was also so so sick with morning sickness couldnt even keep water down so i went to emergency for both reasons. I had to stay 2 nights on a drip coz i was so dehydrated. Anyway they gave me an ultrasound just to check and all was okay and they were able to give me dates, i was 7wks 5days. They told me that you sometimes bleed at the start of a pregnancy when your normal period would be? something like that.

Hope all is okay
