My cycle always lasts for 5 days. I usually have my cycle on the 8th of every month and recently its switched to the 10th for the last 2 months. So for this month my cycle started on the 10 and ended on the 15th. Four days later on Father's Day which was the 19th, my BD and I had unprotected sex and I think we also had sex on the 20th. He did pull out but he said a little of his sperm may have came out before he pulled out. 2 days later which is today i find ALOT of thick white discharge in my private area. Its not like regular discharge, it look like cottage cheese kind of? Do you know what this is???
