I am almost done with my 4th week of being on the mini pill. This is the first time I’ve been on hormonal birth control. On Jan 8, I dry swallowed one of my pills (idk if that affects efficiency), and my bf came in me on the 9th. Today when I went to wipe I saw a small amount of dark red blood in the toilet as well as when I was wiping. Is this normal when on the pill? Could I be pregnant?
