Irregular periods... Will this app still help me conceive?

Teana • I`m 22, met my amazing husband 3 days after I turned 18, we married shortly after and am the happiest girl alive! ❤️
I have never in my life had a regular period. I took my IUD out 12/16/2013, it has almost been 3 months, still not regular and still no positive. I'm getting really irritated. Help?
