When do you guys think I should test?

Cheyanne

We dont really track and since I'm super irregular I'm not sure. I had a bit if light pink spotting that went a bit darker when we had sex but nothing to fill a pantry liner or even be noticable except when I wipe. I've been having some cramps and pains but nothing like aunt flow. I've been exhausted and falling asleep everywhere. I go from having an appetite to throwing up. What do you guys think? Sorry I dont have more info
