what is up witg my cycles?

So, my period came back 10 months after I had akaia. Since December I've had 36-37 days cycle except for 1 month I spotted for 2 weeks and one month was 41 days. Now I'm on day 42, almost 43 and no sign of af. I'm tempted to test in the morning but with akaia still nursing I just don't know if it is worth it or if I should just wait.
