TTC Question! All help welcomed, please!

My husband and I decided it was time to start TTC. I came off of the pill on July 11. I took a couple ovulation tests and was ovulating the dates surrounding the 15th of July. In May and June I skipped the sugar pills an in turn did not have a period for May or June. I still have not had a period and tomorrow will be exactly 4 weeks off the pill and still no period. I don’t want to get our hopes up - could it be!? Should I test? Thank you!
