Hey, me and my SO aren’t really planning for anything to intermediately happen..but we don’t use any birth conceptions.

The last time we did anything sexual ,we did it two days in a role.. Couple days after that, I started experiencing minor cramping.. tender breast.. back pains. And headaches.

My period wasn’t scheduled to be due till a week or so after the symptoms happened. It’s now been 2 days after my period is supposed to be here.. i took a pregnancy Test only to be negative.

Any advice of what this might be ?
