Bleeding.

So I had a transvaginal scan on the 29th November due to pains. They saw a sac and yolk but no baby and told to come back in 2 weeks. Anyway 2 hours after scan I started bleeding not alot but enough to drip a bit on a pad. I haven't stopped bleeding since then. It's only when I wipe. Woman who scanned me said I was early 5 weeks at scan. I've still got pregnancy symptoms. Sore breasts sickness etc. Should I contact docs or wait til next scan ?
