Hi ,
Having
menstruation in 35 days after last menstrual period is considered normal .
Oral contraceptive pills should be taken for 28 days(including 7 iron tab) .
As you had unprotected sex (incomplete oc pill ) and amenorrhoea so do Urine
pregnancy test .It ll show your pregnancy status .If positive then visit a gyne clinic . If negative then take oc pill regularly .if u miss any day then take double dose next day . If misses2cosequetive day then take other
contraception like condom .
Thanks n regards
