Irregular TTC

Tawnee

So, my cycles are so off base, I took birth control for 3 months because from stress, my period didn’t come for 5 months!!! So I took it to start my period! On the third month I only took one week and lost the whole pack!! So I started my period December 4th, a week later... then my period came by itself on January 28th! Which is a 55 day cycle. So I didn’t have a period in February, so I’m like.... HOW THE HELL DO I KNOW WHEN OR HOW TO GET PREGNANT WHEN I HAVE NO CLUE!! I’m not sure what to do... and on top of everything I’ve been having weird symptoms but I’m not sure if I’m early or not to know
