Test now or wait

Maghen

For the last few days I have been feeling really nauseated like I might throw up but can’t. I’ve had cramps, my nipples are super sensitive (found that out last night 😉) breasts have been super warm, even after having my bra off for quite some time.... af was supposed to show today 1-29-19 but didn’t show.. should I wait a while or test as soon as I can?
