Nausea if I'm up doing anything; should I test??

Ive been getting so nauseous if I start doing anything, picking up my daughters toys from the living room floor & even standing cooking dinner I've been getting nauseous. Also I'm so fucking tired. I woke up refreshed and now by 3 pm I'm ready for bed.

No clue when I would start...got off depo bc ; sept 7th was due and didn't get it. Husband and I have been using condoms except one time 2 1/2 weeks ago (the 17th)

Should I get a test?!? Or maybe I'm just coming down with a bug???
