If you're never sure, you should always take a test :) Good luck!
You can get a ept just incase :)
It sounds like you should take a test. Dollar store or 88 cent walmart pregnancy testa work just as well as brand name tests. You could save 8 to 20 dollars and if you are pregnant buy the first onesie with the saved $! :)
Symptoms aren't a good indicator of pregnancy, dizziness, diarrhea, and sleepier are symptoms of pregnancy, but they're symptoms of many things, I'd take a test since you're 2 days late and it will be accurate by now. Good luck hun, I hope you get a positive!!
