I went to get my pills refilled at the pharmacy, but the pharmasist had to call my dr because it has been a year since I last seen him. Well...I forgot to go and pick them. Nine days later I finally got them and took the first Monday pill, because it was Monday. I had intercourse twice in between that time frame. Could I be pregnant? I have been having horrible headaches and feeling nauseous during the day, or is it because I starting taking the pills again after not taking them for longer than 9 days because I had had my period the week before. I am taking low-ogestral. Please give me some advice?
