so I know its probably too early to test. but last night I got 11 hours sleep woke up exhausted still. woke up nauseous and crampy and my boobs hurt pretty bad. I'm not due for my period for another week. and tonight i went from laughing with my boyfriend to crying for no reason in like 5 minutes. I ovulated 4 days ago. Had unprotected sex the day before, day of, and day after. Is it actually possible to feel anything this early? And could I take a test Friday which would be 9 dpo? Starting to freak out with how off I am feeling and did not realize it could be pregnancy symptoms until I googled...
