Birth control / Pregnant?

Steph
I stopped taking my Rigevidon pill on May 19th, after taking it for 6 years, this followed with a 5 day withdrawal bleed 4 days later. I had sex on the 29th and on 2 of my expected ovulation days on 3/4th June. I couldn't wait and did a test this morning which was negative, is it too early to tell yet? could this be a false negative? I've had no pregnancy symptoms but it is only a few days after.
