I lost my child.

back on 11/28/2015. She was an accident. Took me a month after I had gotten off the iud. I wasn't trying. Or anything   But My daughter ended up as a still born. well right after her I met my husband and we have been trying to have another child. Well Ever since then I haven't been able to get pregnant or concieve again.  What's going on? How long does it take after you loose a child?? :(
