Early pregnancy symptoms: help!

Jenny • I'm 27, and I've been trying to conceive for about a year with no luck - YET! 😒😔💔
So, I've read a ton of articles and such about this, and they all mostly say they're the same as PMS symptoms. But I wanted to ask you ladies on here what you personally have experienced in your early pregnancy. 
My boyfriend and I have been TTC for almost 2 years, though not diligently until recently. And I ovulated a few weeks ago, so this is my first missed period. I'm just wondering if it's because I'm actually pregnant or I'm just so stressed out, I made myself late. Wouldn't be the first time lol 
My whole breasts are tender now, and usually it's only my nipples for a few days before AF comes. But it's been like this for a week or more. And my stomach hurts, but not like cramping pains. Way different. Idk how to explain it. What has everyone else experienced right around the time of conception and the few weeks after, before you found out you were expecting? I'm HOPING AF doesn't come and I'm actually pregnant this month. Crossing my fingers! 😇❤️ Sorry for the long post!
