weird periods

so last month my period lasted only lasted for a day and was only light spotting. now it's come around again and yesterday was light spotting but this morning i had heavy clots and severe cramps. and now i have absolutely nothing. no blood, no pain. not a thing.

im USUALLY one of the lucky few that has next to no period 'symptoms' apart from eating everything but im having cravings but cant stomach ANY food which is so weird for me! im also extremely bloated, nauseated, heightened sense of smell, constantly tired... three negative tests over the last month.

WHAT THE HECK IS UP WITH MY BODY?!?😫
