New and unsure...

Lenny • Bloomer, WI
I am new here and me and my SO are TTC my problem is I horribly have missed periods. I can go 4 - 6 months without a peried than bam for a week AF is here so I never know when I'm ovulating or if I even can/am. I'm not sure if this ttc will ever work. I'm sick of looking at BFN's
