I just got my period today and it smells like rotten eggs or meat. I am also having extreme cramping. I have had the same Sex partner for about a year but I think he may have given me An STD. I'm also at risk of having cervical cancer and will get a biopsy in a few weeks. I'm afraid that this rotten smell and extreme pain means something is wrong. I don't see my obgyn for a few weeks now and want to know what should i do?
