Doctors tomorrow

Appointment was originally for to find out why I keep miscarrying 4 times now and the 4th was 16th last month and I found out last Tuesday I'm pregnant again so I've caught straight away, but I started spotting last month and obviously then i miscarried then it calmed down and I'm still spotting since, I feel so down I suffer with depression anyway and I stopped my medication 2 months ago! I just wish and hope to god that this is just nothing, it started calming down today and hardly anything then it's started a few hours earlier it's not bad but just like a light period no cramping or any pain, but with my past it's worrying!!
