Anyone else??

So I've been ttc baby#2 for 14 months now and my cycles are all outta whack. With my first I got off the pill (after being on for 5/6 years) and it took about a year to conceive with irregular periods, stopped March 2013 and a positive test may 2014. But now since January 2015 after having my son my cycles have been normal for a few months then nothing for a few. I did breastfeed for 12 months and I know that can affect it (my pcm tried telling me I can't get pregnant while BF, not true I know). But since I've stopped my cycles have still been off, we have tried everything and are waiting on doctor appts for further testing. BUT, wanted to know if anyone has experienced something similar?? We want to get pregnant asap, our goal was 18 months apart :/ my first is now 16months. 😩
