I had unprotected sex with my boyfriend who is still on meth will that cause me to fail the drug test i have in two days?

I suspect the tiny amount of drug contained in ejaculate would not reach the level required for a random drug test to find it in you.

What you described is unlikely to result in your failing a drug test. If you have additional exposure, e.g., through skin, you may be at risk. You may wish to consider your choice of a druggie as a boyfriend. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines
