Bleeding in early pregnancy after Ivf help!!!

Dear all,
I'm new and am currently 5 weeks 5 days pregnant after 5 day transfer of expanded blast.
My hcg on 9dp5dt was 371 and they put two back.
They told me it was high and I have a scan booked for the 2nd July.
Today I have started bleeding had cramps this morning and then watery red blood enough to fill a panty liner sorry for TMI.
Has anyone had the same? I can't do emerg scan till tomorrow! I've spoken with doctor but she said she needs me to rest and wait until tomorrow and keep a chart of how much blood is lost!
Please can anyone give me advice? Thank you 😞
