Safest way to clear blocked ear when pregnant?

Jennie

Same thing happened to me last year and I used debrox earwax removal kit and it worked. Now I'm not sure if this is safe during pregnancy. What I read online is vague. I could also try hydrogen peroxide but again I don't know if this is safe when pregnant either. I am not having ear pain....it's just blocked with wax :/ I am 7 weeks pregnant.
