Any thoughts? Worried...spotting ER trip

Brianna • Mommy to a girl born 9/12/2008.😇 10/26/18. MMC 5/20/19 🤰🏼 🌈 due in April 2020!

Hey guys I just came from the ER...I went to use the bathroom and noticed some blood and freaked out. I am still bleeding but not much and only when I go to wipe at the moment. They said I should be around 5 weeks 1 day according to my last cycle. They did blood work, urine sample, and ultrasound. They couldn’t see anything on the ultrasound although it may be too early or I’m not that far along. They did say I have a cyst on my ovary and a UTI and my hcg levels were 246. They diagnosed me with a threatened miscarriage. Does anyone have any advice or stories? Is my HCG low or should I not be freaking out. Concerned over here
