Help! Ideas?

So my period is 14 days late. I cry at everything from “someone being mean” to sitting a duck get hit by a car. I broke out all last week and my skin is unnaturally oily. My brain seems to have shut off, someone will tell me something and it takes like 2 minutes for my brain to switch from what I was doing to answer. I’m tired and can’t gym as hard as usual. I want to nap by noon. My dad and his girlfriend told me I was pregnant. I’m one of 3 and was told “ I know these things” and my husbands thinks so too. But all my pregnancy tests are negative. Thoughts?
