Hi everyone !

This might be kind of long so i’m sorry haha. I know I shouldn’t really be worried. however, weird things have been happening lately that hasn’t happened before. Okay so last month i switched birth control brands. i’m on the pill. I’ve been on it for about a year and i’ve never had period symptoms until i recently switched. last time i had period symptoms was when i wasn’t on birth control. could this mean the pill isn’t working ? i had sex 2 weeks ago with a condom and he pulled out and i took all of my pills on time. i wasn’t nervous until my ovaries started hurting which also never happened while i was on birth control before. i did get my period the very next day after i had sex. however, i know people say that sperm can last a little while. now i’m spotting two weeks after my period. what could this mean? i’m just a little confused because i was being super safe. could my birth control stopped working ?
