Messed up period

For starters, my husband and I are trying to get pregnant with our second child and have been trying since October. I stopped taking birth control in September.

My periods are not regular by any means but are usually around 2 months apart and have been this year. I've thought I was pregnant before but they just turned out to be PMS symptoms. Like my last menstrual cycle, my boobs hurt for 2 and a half weeks straight before starting my period which threw me off because usually they only hurt the day before and then stop when I start my period.

Fast forward to this cycle, refer to the picture below, I already feel like something is off/different. I dont have our days we have sex accurate on this app, but we have done it frequently. I was spotting on the 15th and the 16th and that's definitely not something my body ever does. I dont even spot when I'm about to start my period, it just starts out as a murder scene. Today I woke up with some mild cramping and I'm bloated without a doubt today. And couldn't eat what actually sounded good for breakfast. I got halfway through a sandwich that sounded so good and had to start spitting it out.

Has anyone with irregular periods dealt with this while TTC?
