So excited to try again but confused..

So, now 2 cycles after miscarriage I'm TTC for the 2nd month 😊. I'm very excited to see if we get our rainbow baby in July!

I got a d&c done May 17th. I got my first period June 7th, then again June 28th. So twice in one month. Has that happened to any of you ladies? I'm now confused about my fertile window. I ordered opks but am assuming they won't get here in time this month. My next period is expected July 22nd (I think).

Has anyone else ever gotten period twice month after d&c? Or maybe was the bleeding from the 7th not actually my period?
