Threatening miscarriage

Hi guys! First off congratulations to all of the pregnancy announcements. I found out I was pregnant on January 12th. I have pcos and after losing about 90 pounds my periods came back “normal” in August. My husband and I have been trying to conceive since September. Well fast forward to the 12th of January I found out that I was pregnant. This passed Thursday I visited my obgyn and did an ultrasound and you can barely see anything which she said I was early so she wanted me to do blood work Friday and again tomorrow morning. Well my urine test were all very faint so I didn’t really expect much anyways. She was thinking I maybe ovulated a little later in my cycle which is cool. So yesterday afternoon I went to the bathroom and noticed that I was spotting bright red and pink no cramping. I went to the emergency room yesterday they drew my blood and said that my hcg levels were really low at about 134 and I had an ultrasound which showed the gestational sac in my uterus so the ER dr basically said that I may be early and diagnosed me with a threatened abortion or in other words miscarriage. I am not cramping but every time I go to the restroom and I wipe it’s a little bright red there and I’m trying not to stress but I can only hope for the best but expect the worst. I have to do blood work again tomorrow. Has anyone ever been in these shoes and if so what happened?
