I’m scared

Took two pregnancy test the second week of this month. Both came back positive, I was so happy since I had an ectopic pregnancy November last year. 2 days ago, on my way to work in the morning there was thick fog to where you could only see 5-10 ft ahead of you. Caught up to a stop light but I noticed the car behind me was coming in hot so I got super scared that I was gonna get hit, was shaking the whole way to work because the driving conditions where horrible. Finally made it to work and 20 mins in I started spotting?? At first it was dark brown spotting, then I went for my 1st ultrasound the next day and saw our baby’s heart beat!! It was such a relief to see it, my progesterone levels were low so I got prescribed and now today I’ve been home sleeping and being lazy. Well about an hour ago I felt a gush getting up from out kitchen table so I went to the rr notived a clot of blood on my pad. When I was done I came to the bedroom and just as I’m about to get a new pad I just feel blood coming out of me so rush to the shower and I’m bleeding a lot! Also I threw about 4 more clots. I’m not in terrible pain because I still feel the shocks I’ve been feeling ever since I found out I was pregnant but sometimes they are a little stronger than usual so I’m wondering if maybe I am miscarrying or what is going on with me? Any moms had this happen in the past? If so what should I do?

Already left a message with my Obgy.... I’m trying not to freak out as my husband and I have already lost a baby back in November.
