I miscarried May 4th and it lasted an abnormally long time (doctors think it was possibly an ectopic that resolved itself after finding a mass in ultrasound)

So i have only had 1 period since then. This was our first month cleared to try again and now my period is 2 days late. I have been testing like crazy and getting nothing but negatives. My period almost always arrives every 28 days exactly on time so this is something new.

Did your period cycle change after miscarriage?

Should I give up hope for this month because I should have gotten a positive by now?
