I looked up the symptoms for a sinus infection and I had all the symptoms, so I went to the doctor but he just looked for 2 minutes and gave me antibiotics. The thing is I've already been on antibiotics 3 times this year and I'm also on a contraceptive pill so isn't this really bad for me?

Is it ok to stop taking antibiotics now (I've been on them for about 3 days now)?

Some antibiotics can make contraceptive less effective and if you are concerned; I recommend you seek a second opinion. However; if you looked up the symptoms for a sinus infection and believe you have one....antibiotics are the only way to clear it up.
