Bleeding after BM

(Long read ahead, sorry in advance)

So a little backstory first. I had an early missed miscarriage at 5 weeks in July. I am now currently 9.5 weeks pregnant, and everything has been going perfectly so far. The baby has measured on time, and the heart beat had been 166-170s when checked by the US techs.

Yesterday I had been lightly cramping for most of the afternoon, and had quite a lot of clear discharge. I know discharge is normal, so I wasn't too concerned. When I got home from work, I went to the bathroom (I have been constipated due to progesterone), and passed a BM. At this point my cramping was worse, but I thought it was due to constipation. When I wiped, I saw bright red blood, but it was watery. I triple checked, and it was in fact vaginal blood.

After cleaning up, the blood went away and didn't come back, however, my cramping was getting worse. I immediately grabbed my husband and went to the ER since this is similar to how my previous miscarriage started.

After getting to the ER, they drew 6 vials of blood, and performed an US. I didn't get to see the baby, but my husband did and he said he could see the heartbeat, but couldn't tell how it was measuring. We asked the tech for details, but she said she couldn't tell us, that the results had to come from the doctor. So we thought, "Okay, guess we will just talk to the doctor."

Three hours later we were finally put in a room. Due to how long it took, we assumed that meant the baby looked okay and we should be receiving good news. At this point I had calmed down, and waited patiently to talk to the doctor. After getting to the room, the doctor gathered a brief history, and said "Okay, let me check the results, and I will be right back."

45 minutes later a nurse comes in with my discharge paperwork. He told us that the US looked good, and that I am having a threatened miscarriage. At this point I'm confused, because no pelvic exam was performed to check my cervix, and I have not seen any test results from blood or the US. The paperwork told us to follow up with my OB in a few days, but other than that I received no answers or instructions.

I have done a little looking at other women who have experienced this, and have seen cases of sensitive cervix, but they didn't have severe cramping like I am. As of now, I have not bled since the BM. I am trying to calm myself down, but having the diagnosis of "threatened miscarriage" thrown at me with zero explanation makes that difficult.

I guess what I'm trying to figure out, has anyone had a similar experience and everything turn out okay, or do I need to be worried? I won't be able to schedule an appt til Monday, and that means I probably won't be able to see the doctor until Wednesday or Thursday, so I'm trying to make sense of everything until then.

SORRY FOR THE LONG ASS POST. BUT THANKS FOR HEARING ME OUT 😭
