What do you ladies think is going on ??

So my last period was May 4th through May 11th. May 26th I went to the restroom and wiped very light pink blood. I haven’t had anything else sense, I’ve taken 4 test and all negative.

Period was due June 4th.

My periods are usually very heavy so I can feel them coming. But my body just feels different, I’m bloated 24/7 I have light cramps that will last not even a minute(my period cramps are usually like death and are constant)

What do you think is going on, what should I do!?
