Still no period??

Brandi

My sweet little Beau will be one on 6/9/18. We are still breastfeeding along with formula and table foods. I still haven’t started my period... I’m not on birth control but we do use condoms, (but tmi only after things get started a bit if you know what I mean.) I started spotting and cramping a bit yesterday and thought for sure it was my period but now I’m just crampy with no blood. Any ideas??
