Hello. It has come to my attention that my period is now 7 days late. I usually have a regular cycle of 28 days but I am now on the 36th. Mind you, my last cycle was 33 days and I was quite stressed during this time. My last period was May 9th-13th. It is now June 13th. I lost my virginity to my boyfriend on May 20th. We used a condom and he pulled out before he ejaculated. I also checked for tears/holes before and after intercourse. We have had sex a few times since then, and we always follow the same procedure. We also did not have any direct contact between genitalia. I am having my usual PMS symptoms such as tender breasts, slight cramping, and (sorry) constipation. Although every now and then the constipation goes away. I need peace of mind. Please help.
