Hey Girlies! So I started back on the patch contraceptive in November on the 10th to be exact then 8 days I got my period in November well, 10 days after in December I had a period at the beginning after that 16 days later I had another one which is two for that month of December. January it was 28 days until I had another one. Last month period late by 8 days This month my period is late by 11 days and I’ve been having protected and unprotected sex i know my period is irregular so just wanted opinions on what everyone thinks, thank you in advance!
