Help! I'm 44 years old, my cycle started on 7/14; 7/19 or 7/19 should have been my last day. I'm still spotting, I had a root canal done on 7/13 and started taking Penicillin on that day, for 10 days. Could that be the cause of the spotting? I am schedule to go on vacation in 2 days and I need the spotting to stop, my boyfriend lives out of my state and we are long awaiting this trip....what should I do. Is there something I can take to stop this spotting immediately. I have no cramps, but my breast are a little bit sore. HELP!
