Bleeding after BFP?? Has this ever happened to anyone and not ended in a MC??

Shari
I am very nervous because I tested positive on Thursday (DPO 14) and today with a slightly darker line. I also had some bright red bleeding in morning. By the evening I didn't see anything. Going to doctor on Monday and went for blood test on Friday. It was late in the day so I did not get a HCG count yet. I have had two miscarriages in a row. This time however I am on Progesterone to help. I am just wondering if anyone ever experienced bleeding like this very early on and everything turned to be ok. Just hoping for some positive stories since there is nothing I can do but wait.
