I'm 20 and just got off birth control in December and started trying to get pregnant in February but nothing. Not sure what it means by periods being inregular I go 5 days. But sometimes my cycle is between 28-30 days. One month 28 next month 30 next month 29. So it's kinda hard I guess to tract ovulation but we have sex pretty often. Guess what I'm asking is should I be worried about not being able to get pregnant? How can I tract ovulation. We haven't been trying for to long so Google lol tells me it can take up a year for someone under 35 to get pregnant. I guess I just need some tips. It's so disappointing when I get AF. Got her today. :(
