How much isn't good?

So this is my third pregnancy after 2 losses. I'm in the state of mind of "I don't want to know if it's bad news"... so I've gotten quit a bit of dark brown discharge over the last week or so. Usually in the morning and gone in the afternoon. But today it's 1:30 and I'm getting more.

I've hesitated calling my dr office because I'm terrified of going in and getting bad news. I had a MMC last time without knowing before I lost.

I don't want to go through that pain and emotions of losing again so I keep talking myself out of going.

I have a regular apt with my OB on the 24th and I keep telling myself I'm just going to wait till then to say something and see if we can hear a heart beat.

I have a sub chorionic hematoma but haven't bled since the last bleed at 7+1 (currently 9+4) so the dark brown I keep thinking it's just that. No cramps or clots.
