I Need some advice please

So me and my bf had sex on the 22 of Jan but the condom broke. I started ovulating on the 26th and I'm currently 5dpo. Yesterday I noticed a light pink color after wiping, it wasn't a lot. The day before I got very dizzy outta nowhere. Yesterday and today I've been having some crazy headaches. I've also been cramping a lot. I also noticed I've been tired more than usual also very moody. I don't know what to think
