Hello,

if you have problem with irregular period then I suggest you to go on birth control to regulate your period .. But if you worried that youre pregnant, then do some hpt .. Good luck

I'm confused. You had your period from dec. 18 until jan. 16 or 17?

Anyway, weight can have a factor in random periods. Mine have never been regular, either. The more you stress, the later it will be. Take a test if you think you're pregnant and, like ms_sweetie said, get on bc if you want to regulate the periods. It worked for me.
