Implantation bleed

Please help!

I’ve had two previous miscarriages. One at 6 weeks another at 4. I’m currently taking progesterone cream and ovulated on the 12th Feb. I’m have slight symptoms of pregnancy but it is early yet. I have just wiped and had this discharge. Could this be implantation bleed? I’m currently 6dpo. I really hope it’s not another chemical coming if i am pregnant. I’m able to test on Saturday.
