Ok so this is my first month starting Loestrin Fe birth control. After one week on the pill I started having unprotected sex (while also pulling out). I take my pill between 10 or 11 every night. So I started having old blood spotting for two days before I had new blood actually come out. My period is really light. Although it is new blood, should I still be worried? Is this considered spotting or my actual period? HELP
