Hi there, This is Dr Basu, Experienced Specialist. I am here to address your concerns and provide great service.
The risk of pregnancy is very low.
Your are on placebo pills that too on first day.
So microgynon will still work well.
Penicillin will not significantly affect microgynon function.
Your risk of pregnancy is less than 1% in practical terms.
You are way out of ovulation as well meaning you do not have any egg for fertilization.
Please do not worry.
