Late & sooo confused!!

Jacie

I’m 3 days late on my period (I have been strictly on time for the past 6 months I’ve been tracking), I have these cramps that feel like period cramps, but nothing! Then yesterday I got a little bit of blood in my CM, but again that was it. What is going on here?! All my pregnancy tests have been negative so far. I feel like it would be positive by now if I was pregnant. Any advice? 😬😬😬
