okay so i put the ring in on the 18th of april. and im supposed to take it out on the nineth. but i just started spotting i noticed it when i woke up this morning. i also drank last night and had unprotected sex, my bf did bust in me. so is there a possibility i could still get pregnant? although afterwards i replaced the ring right after didnt wait to replace it. do i have anything to worry about or am i going to the hospital? ive had symptoms of a period the day before the pre cramps bloating and cravings. is this normal?
