i started taking amoxicillin for my tooth infection two days ago. I already had my period for this month and I am bleeding and spotting. Is this normal?

Yes, if you are on birth control pills, this is normal because antibiotics decrease the effectiveness of the Pill. Many women on the Pill will experience breakthrough bleeding when on antibiotics. If you are on the Pill and you take antibiotics, you should use a back up barrier method, like condoms, for the entire time you are on antibiotics and for seven days after you finish them or you could become pregnant if you are sexually active during this time.

Antibiotics should have a BLACK BOX WARNING: Reduces efficacy of oral contraceptives. Always use backup method until next pack. Double barrier such as condom* and spermicidal foam or diaphram and spermicidal gel. Same is true after even minor bout of diarrhea.
*Note - Condoms, alone, and when used properly are only useful to prevent the spread of STDs. To prevent pregnancy, double barrier method is required. Condom must be worn prior to any physical contact with areas near genitalia, and removed immediately after ejaculation, penis still erect to prevent leaks and spills that cause pregnancy and disease. If more groups distributed this vital information, instead of "abstinence only" literature or photos of aborted feti, the cause would go far to prevent unwanted pregnancies and abortions no one wants.
