What can I do? TTC for 6 months

Alyssa • Hi! I`m Alyssa! I`ve been TTC for about a month. I am taking prenatal vitamins and eating healthy.
My names Alyssa. Me and my husband have been trying for 6 months now but still nothing. I need some advice. My periods are VERY VERY irregular. For example: November 5th to December 8th -33days 
December 8th to January 27th- 50 days 
Skipped February 
January 27th to march 5th- 38 days
Skipped April
March 5th to May 15th- 70 days
(NOTE: my periods only last 4 days.)
So as y'all can see they are very irregular.
I have used the clear blue ovulation kit 3 times. The kit always gives me a solid smiley just 4 days after my period. 
I have tried several ole wives tales but still nothing. Does anyone else have this problem?? What can I do to regulate my periods?? I read online that I might not even be ovulating because my periods are so irregular. What can I do?
