Does anyone see anything?

Okay ladies, 
 'm on cycle day 12 and according to glow in not supposed to ovulate until the 24th but this morning I woke up and instantly thought I was going to be sick. I was extremely nauseated and although I didn't throw up I still feel like this. I ate some lunch and thought I was going to be sick afterwards. Nothing even sounds appetizing to me at all today and I've had a slight headache. I'm unsure whether to take a test or if it's still too early. I just dread that BFN. What do you guys think?? Has anyone else had these symptoms before you found out you were expecting? Thanks!
