Baby on the way ? :)?

I had unprotected sex 3 days prior to ovulation. No birth control or any means to prevent pregnancy. It's now 9 dpo. I'm extremely fatigued and want to sleep all the time. My lower abdomen is bloated and feels heavy. My boobs don't hurt but my nipples are sensitive And i experienced some cramping yesturday not bad but kinda like period cramps. And I've noticed alittle extra discharge. No spotting. I know it's to early to test. But if someone could give some insight to help me feel not so crazy would be wonderful. I have my fingers crossed that this may be it :)
