7 weeks, Red bleeding and lost mucus plug

Brittany

Can anyone who has had similar happen to them, share their experience? I’ve had red and brown bleeding for 5 days now. The first day was lots of red bleeding with clots and went to the ER. Got diagnosed with threatened miscarriage, and sent home. Two days later, got follow up ultrasound and they detected a good heartbeat and said it’s viable. Then I had a small amount of red bleeding then brown, and now today day 5 of this I had no bleeding until an hour ago. Went to wipe after peeing, and a loooooong string of mucus that looks like a plug (compared to google pics of plugs) and then some red bleeding again. Is this certain doom? I feel like I’ve already badgered the doctors enough :( they told me to go back to ER if the bleeding is severe or painful, and it’s not, but losing the plug feels really scary! My first pregnancy with my daughter had none of this going on so I’m extra freaked out.
