I just turned 20 years old and I just had my first sexual intercourse last june 3. My next period after May 13 was on June 20 , which is not normal for me because I usually have a 29-day cycle and the may-june cycle was a 38-day cycle. my boyfriend and I had unprotected sex during june 25, 26 and 28. He ejaculated on me last july 21 and 24 because i know i am not fertile on these days. And now, I am on my 35th day of my cycle and still didn't have my period yet. Also, I am feeling dizzy most of the day and a little nauseated. Could I possibly be pregnant or is it just simply delayed like the last time?? Is the sex on the days I did it safe or not??? I'm wondering and kinda worried now.. :-(
