Regular period (started 6/29) Taking 3 different antibiotics (since6/22) but forgot to take them today. Had unprotectedsex 2weeks ago. Just throw up. Y?

What is the question. Are you concerned about missing the antibiotics or the possibility of pregnancy? Neither taking nor missing the antibiotics changes the risk of pregnancy if you have unprotected intercourse. It must be a serious infection to require 3 antibiotics. You need to continue the antibiotics as prescribed and follow up with your doctor to be sure you are adequately treated. Hope this helps.
