Post partum migraines

I finally had my first PPP a couple of weeks ago and since have had 2 migraines. Neither was severe but both lasted several days. I am still breast feeding so my cycle is likely pretty wonky, but this doesn't seem normal to me. I have had migraines in the past but not in a long time and never this many. Has anyone else experienced hormone fluctuations causing headaches after the first return of AF? I'm not sure at what point I should become concerned something else is wrong with me.
