Welcome to HCM.
You were on Microgyon 30EG birth control pill over 3 yrs. You started new pack on 18/6,then took antibiotic for 5 days & did unprotected sex and after that missed pill on 1/07.
So chance of pregnancy
is there,although very little as intake of antibiotic may reduce efficacy of OCP
, beside you missed pill and did unprotected sex around ovulation time.
So wait for the upcoming period and if missed,then do a home pregnancy test with urine after 7 days of period date.
Check the result and consult with your doctor according to need.
Practice safe sex
in future with using condom as extra protection and if you missed one pill,next day you have to take 2 pills.
Be well & TC.
