2 months no period, negative tests

i stopped my birth control november of 2017 due to some traveling and i forgot it and decided i felt better without it and i had a lot of unprotected sex with my boyfriend. i had no period for the longest time. my cycle was running close to 60 days. i then tested at cd 62 and all negative. i decided to continue with my birth control despite not having a period and now im at the point in the pack where theres suppost to be a period and im almost at the last day with no spotting or anything. should i test again? or would it be a waste of money
