Starting on Thursday I started having cramps and heartburn so bad that I couldn't get up from my desk chair. I have very irregular periods so it's hard to tell when I am due to ovulate but glow told me it was around dec 12. We had sex on dec 11. Today I started feeling some nausea but didn't actually throw up, I just felt like I was going to. Should I test or wait for more consistent symptoms? I've been tired and felt like I needed to pee more often. Any other ladies out there with the same type of thing?
