HELP HELP HELP

We've been trying to conceive for almost a year now but it's taken ages for my period to return after being on birth control. I got my first true period last month and had sex during ovulation. 10 days after this i had dark brown spotting for a few days and now my period is 2 days late. I'm getting my hopes right up but about 10 tests says I'm not pregnant. HELP! Should I keep testing or time for doctors? Please give opinions ✌🏻️👍✌🏻️
