27w1d

So I had a horrible start to 27 weeks. Everything was fine yesterday, then when I got home after dd's therapies down the cape I went to the bathroom and saw bright red blood in my underwear. I thought oh no this isn't good. And as expected there was blood in the toilet after peeing. I immediately started to freak out. It is one thing to bleed from a SCH, it is another thing to bleed at 27 weeks.
I called up the hospital but they told me because of the drive it was best to go to the local hospital so I did. They had me hooked up for 3 hours, everything looked fine with the baby, cervix is closed and the spectrum exam looked like the blood was turning darker old blood. The Mfm on call though wanted me to go to Providence to be further ministered there so I had to be sent by ambulance - this is starting to remind me of last pregnancy :( I then spent the next 3 hours in triage there where they repeat all the same stuff plus did a portable u/s exam that showed everything good. The resident had no words of advice and basically said this happens sometime.
Anyways they kept me for the night. Tried to put those stupid inflatable boots on my legs but luckily the machine kept acting up so they took them off at 1 this robing. The bleeding dried down over night. Went to only a small amount of pink and then nothing at 4am. The doctor came at 6 this morning still not helpful and with no explanation and basically said if everything looks good after the next few hours I can go home.
I then went to the bathroom again. And the red spotting/bleeding started again. Not as bad as when it first happened but there when I wipe and some going into the toilet so I don't know what to think or do. I don't think I can deal with this anymore without knowing where this bleeding is coming from. And how long it will last.
