Period Problems

I am currently breastfeeding my almost 19 month old and just got my first postpartum period on May 1st. I typically do not get my period while nursing, but I also haven’t nursed a baby this long either. I’m hoping to conceive again soon, so I’m just trying to figure this out. I tend to have long cycles, so I expect that I ovulated after day 20-25. I have had intermittent cramping since then. I have had breast tenderness and fatigue for at least a week, if not longer, at this point, but still negative pregnancy tests. Emotions are all over the place. I’m losing my mind waiting on something. Whether that’s my period or a BFP...idk
