Am I out or could it be implantation bleeding?

Julie • Currently pregnant with #2 our 🌈👶🏼

I’m a little puzzled. I have a DD who’s 1.5 now. I had a miscarriage in December and got the go ahead in late January to try again. Ive been feeling all the pregnancy signs without having a positive test. I know it could still be too early to get a positive, but I tested this evening anyway(just can’t help myself 🤦🏼‍♀️). I was surprised to see bleeding when I went to test.

Could this be my period early? I used opks to test when I ovulated. My current calendar is correct. Did anyone have their cycle be shorter in days after they had a miscarriage? I’m sure hoping this is implantation bleeding, but I’m scared I’m out for this month. 😭
