I started taking amoxicillin for 7 days on Friday 18th Dec . I finished my antibiotics on 24th Dec. I took the last contraceptive pill in the pack on Saturday 19th Dec and had my 7 day break. Started taking the next pack on the Sunday 27th Dec and had uprotected sex Saturday night/Sunday morning 2nd-3rd Jan. Is my contraceptive compromised because of this and taking antibiotics on my 7 day break??
