Period question

I just had my babygirl in March ... sadly I had sex before my 6 weeks was up but every time I had sex we ended up buying a plan B . In April I had my period 20-26 then I bled again May 4th for a few days . I haven’t had a period since then . On June 8th I started spotting it was light pink and other times it was just a wipe of red . But no actual bleeding . Should I be concerned or is this normal after a baby
