TTC with irregular cycles

Just when I thought I️ was finally becoming regular my body has to mix it up a little. I️ used to spot for my entire cycle light pink blood. That finally stopped three months ago but I️ bled for almost 3 weeks. That new cycle was perfect no spotting. I️ got sore boobs during my tww and then spotted just a few days before my period began. Last cycle was just as normal. My boobs hurt for about a week and a half I️ spotted just before my cycle started. This cycle I️ should have either started or will start within the next few days and I️ have absolutely no symptoms pregnancy or period. So I’m not sure if I️ won’t bleed or if it’ll be a long cycle or if I’m pregnant.
