What's wrong with me

November 27th I got my period for that month & then I got another period 2 &1/2 weeks later on December 18th and here it is 2 &1/2 weeks later again on Jan 10th and I started my period. I'm so confused. It seems like ever since me & my husband have been TTC, my period is all messed up and it kinda worries me like I can't have kids or something bc I'm so irregular. 😔 idk what to do.
