TTC but BF and no AF return.. possible??

I really want another baby but firstly, DD is only 5months, and we are exclusively breastfeeding. I haven't had AF return yet.

Is it possible, or should I give up and just wait for AF?

DD feeds every 3 hours, but at nights she has ONE 5hr stretch.

Also, should I/can I take elevit? While BF?

Hi
It is possible, but only if you ovulate, which can happen prior to your first period. So, you will need to watch out for your fertile signs and.... wait. It's impossible to predict, but your cycles may well resume fairly soon.
No problem taking elevit when bf.

everyone is different...
some women can conceive whilst exclusively breastfeeding and some can't.
With all of my children, I have not had cycles return until I finished BF so I could not have conceived whilst BF. But you may find your cycles return soon.
Basically though, you might as well not worry about TTC until your cycles DO return because you can't ovulate and NOT get a period. Once you ovulate, you'll either be pregnant or you'll get your period. so if you wait until your cycles return, you will only have missed one single solitary chance at conceiving.

good luck!
