Pregnancy symptoms after depo

Tesha

I have been off depo since September and i just ovulated a week ago, but i have had sore boobs, nausea, and just started getting motion sick in car rides, all symptoms i had when we were pregnant with our son. But it took 9 months to get pregnant with him after depo. I took one test that looked somewhat positive, but was an old test so I bought more and took another test less than a week later. That one was negative. Should I wait another week and retest? Also, have not gotten my period.
