Feeling Crazy

I feel like I'm crazy. For some of yesterday and all of today, I have been feeling a different sensation in my pelvic area. It's almost constant. Not painful at all. It's hard to explain what it feels like, have felt pressure only a few times, mostly feels like a twinge or flutter. It is not an upset stomach, but I keep trying to convince myself it is because there is no way I could be at implantation. 
I have been TTC for 3 months. I do not do ovulation tests, so not sure when I ovulated. One app said my most fertile say was Friday, the 5th, but Glow said it was Saturday the 6th. First day of last AF was 5/24. 
Then I came across this article. Am I freaking crazy or what?!
