Help!!!

My periods ‘normally’ jump from anywhere around 28-32 days (and even longer in the past), currently I am on day 37 and no period yet, tho I have had alll the symptoms that accompany Aunt Flo, she hasn’t shown her face yet, I have no pregnancy tests at home, only the ovulation tests from my last child who is 15 months, I’ve heard that you can get a positive result on the ovulation tests if you are in fact pregnant, so I tried this method since I live 30 miles from any town with any pg tests, am I pregnant? We are NOT trying to conceive so this will be a huge shocker for us, and I currently still nurse at nap and bed time.
