pink discharge?!

Samantha
I had a miscarriage last Wednesday (22nd March 2017). We've been trying like crazy to get pregnant again. 
I know the doctors told me to wait a month so they can figure out a due date. But tbh it was stressing me out and making me depressed having to wait. So we've just dived right in.
The MC bleeding stopped on the second day as they removed most of it at the hospital. 
Now, yesterday I got a little bit of pink discharge. I'm not sure what the hell it is. Could it possibly be implantation bleeding? We only started having sex again on Saturday, would it be too soon for implantation or can you bleed from conception?
I don't know! I feel like I'm getting my hopes up but I'm so excited and I can't find anything on the internet.
