Hi! Im delayed for a week now. What are the possible reasons of having a delayed period. Anyways, my boyfriend and I had a unprotected sex on my second day of cycle. but he pulled it out. on the 21st day of my cycle, I had a discharge of blood and on 33th day of my cycle i took pregnancy test, took it in the morning and got negative results. im usually having 27-31 days of cycle. What are the chances? am I pregnant? Thanks!
