Periods never cane back!

So we had pur baby last January and I thought my cycle would be back on track by now... But nope!
I don't exclusively BFeed, although my baby drinks SOOOO much. But still, seven months... Shouldn't it be back?
We are trying to conceive again and not that I mean to complain abt how we go abt conceiving, but I'm starting to think its all in vain until my cycle is back on track... Any advice? Anyone relate to this?
