TTC but all of a sudden irregular cycle

Madisyn

We have been TTC for 11 months for baby #3. We had no trouble with the first two now having trouble with this one. My dr sent me for bloodwork which I got done this morning to see if I’m ovulating enough. My periods last almost always 25-26 days. Today I started bleeding dark red almost brown and it’s not just spotting. Does anyone have any idea why I have two periods in one month?
