Period And Pregnancy

Okay ladies this is just one of those talks i would usually have with a close friend but i have no friends so ya can be my friends now 😂 for the last couple years my period has been irregular. I don’t even think I remember the last time my period was regular. Im now 21 and all of a sudden the last 3 months my period has been regular, 30 day cycle, lasts about 4 days. Hubby says he think i will get pregnant now that my whole vagina system decided to change courses without even consulting me. Anybody else got pregnant after there period changed from irregular to regular? Lol Also this may be TMI but 3 days ago i realized i been peeing more than usual which is annoying, and realized my kitty been more wet than usual too. Is it me or I’m just overreacting...
