what is going on?!

im 11 weeks and 5days yesterday i woke up from a nap thought i had peed my pants when i stood up went to the bathroom and turns out i was bleeding....ALOT no cramping no clots at all i had bled earlier in my pregnancy around 7 weeks or so. well this was alarming i went to the ER and they said my HCG levels were good over 77,000 and they said my cervix was closed, and they found baby on doppler monitor. i see my actual OB dr tomorow. i have no clue what's going on. today my bleeding is minimal again. 😭 very worried
