Spay complications

My dog was spayed 5 days ago and day 2 she had frequent urination with very little coming out, took her to the vet who checked her pee. Had blood no bacteria but put her on antibiotics anyway. Layla was in heat when spayed and is bleeding vaginally, so unsure if blood is actually in urine or mixing when it comes out. Vet also gave iv fluids and antiinflammatory shot. Urinary problems went away that night. Next morning there was a blood tinged fluid coming out of the incision site and I took her back to the vet. Vet said it was fine and to keep her more calm(which is impossible because she lays down all day and night and only gets up to pee and I carry her in and out for that) So I took her home and watched it as it continued to ooze. Every movement causes it to ooze a little. Her vaginal bleeding also got a little heavier and is red brown in color, I continued to call the vet because I felt something was wrong and was told repeatedly it's fine it takes time to stop oozing and dogs can bleed vaginally 7-10 days. Also prescribed a heavy sedative to help her stay asleep and calm. At this point I have been syringe feeding and watering because she is disoriented and does not get up. Today she did eat a good bit and actively licked the syringe with water to get more. I am so scared about all of the bleeding and oozing so I consulted a second vet who said without doing anything other than a temp. which was normal, that she wanted to open her back up and see what is going on and it would be 1700!!! The spay, biopsy, and pathology was only 500! I was shocked at how quick she was willing to open her up without being able to really come up with a good reason why. Also my vet said the fluid was serous fluid from a seroma but there is no swelling and when I asked the second vet about it she didn't know what it was and changed the subject. So I of course left and did not have the surgery, but I am still scared. Is the oozing and vag. bleeding ok?
