Hi, im a little concerned ive been taking the pill carazette for 2 months stopped taking it as it was giving me bad headaches and making me feel faint. I blead quite a lot whilst being on it. Anyway I stopped bleeding for about a week & now im getting thick brown discharge , and I have had unprotected sex about 2 days ago. I also have a 10 week old son,and I believe that it is really easy to get caught again. Is it possible I could be pregnant again?
