Regulating after birth control

Crystal • TTC # 1 since 10/2014 with my wonderful DH of 3 years (together 11). So excited to start our little family <3 <3
So I stopped my birth control right at the end of October/beginning of November 2014 and patiently waited for AF to show herself... which she did, barely, in January. And exactly 28 days later in February. Now I didn't pay a whole lot of attention to the regularity of my cycles prior to being on birth control, because I was young and in college and just didn't care. Now about 2.5 years later I'm clueless as to when to expect AF. I thought maybe I was regular, after my last 28 day cycle, so me and my DH went by what glow said should be my fertile days and BD'd away. NOW I'm on CD33 wondering what the heck is going on with my body. Got a BFN yesterday. Was nauseated of and on the past 2 weeks and yesterday/today i feel like I'm coming down with the flu. I'm thinking maybe it's my nerves, I'm very type A and hate having no control over any of this! Anyone else going through the same struggle? I just want to be a mommy :-(
