I started taking my birth control pills on December 29 had sex without a condom January 4th (a week from when I started taking them) he did ejaculate in me. Yesterday I was on the third day of week three and I was spotting and had discharged (brown/pink) this morning is till brown. I’ve had sex without condoms at least 3 times since I started the pill. Next week I start the pills that are a different color and my doctor said that week I should be getting my period. Is this normal or should I worry about pregnancy?

Also just now I ate a fried egg with toast and threw up the minute I finished (didn’t feel sick or anything before eating or after throwing up)
