TBH I would be surprised too that my friend wasn't going straight to hospital and I'll explain why.
In my first pregnancy I started bleeding at 8 weeks. I was on the phone (4:30) to my other half and had to say "TD shut up! I'm bleeding!" It took several attempts for him to shut up and listen.
I called my GP and the receptionist said to come straight in, a worker from the block I was living in said she'd walk me around - I'd just had a row with her and she felt guilty (even more so when Mum nearly killed her later).
Sister met me half way to the surgery, Mum just before I got there and TD just after I got in (just to get distances straight, sister worked around a 1.5 miles away and was in a car, TD worked 1 mile away and was on foot, Mum works about 3 miles away and was in a car, surgery is about 1/4 mile away lol). I was sent straight into the next Dr who sent someone out. She said my cervix was closed, to go home, rest and go to A&E if the bleeding got worse.
My sister took me back to my parents house and before long I went to the toilet and couldn't get up for 15 minutes because I was bleeding so much. Mum came home (5:45) and took me straight to A&E. Bypassed triage, sent straight down to the cubicles.
Spent some time in A&E while they did a water sample for pregnancy test and got a canula in my arm (ward refused me without it). At 9pm I was on the ward being examined and Dr removed one of my babies, I had lost one at home and a scan the following morning found another but they weren't sure if it was alive, I lost the third a few days later.
I had a second pregnancy I lost at 20 weeks, which was fairly symptom free - apart from the odd TIA, which I didn't know at the time.
Third pregnancy I was on aspirin and Clexane (heparin). Because of that I bled everytime I had sex or an internal. It took awhile to realise what it was and for awhile everytime I bled I went to hospital. The first time I called the out of hours GP and they arranged for me to be seen on a ward as it was a Saturday.
Maybe my history has coloured my view, but when I first bled there wasn't any colouring and I still went to hospital, it wasn't heavy at that point either. It might not change anything to go straight to the hospital, but they can get you on a drip if you lose too much blood etc.
