Missed last two periods!

Brittany

My husband and I have been TTC for about a year. My cycles are irregular 30-40 days usually but I haven't had any period since May 26th.

I've taken multiple pregnancy tests different brands for the last two months and all are negative.

I have an appointment with my OB/GYN on Monday to see what's going on.

But I was wondering if anything like this has happened to anyone? Or if I could be pregnant?
