Many women have anxiety about pregnancy when they’re perfect users on the pill. I wouldn’t say it’s okay, because it’s causing you anxiety, but it’s definitely common.
As long as you took your pill correctly you’re completely protected, so there is no reason to worry. The pill as a stand alone method is actually more effective than condoms.
Have you researched how the pill works scientifically? That usually helps people trusting their pill. Until you trust your pill you should use condoms to ease your anxiety in the future x
