My last period was June 5 2014. It usually lasts between 5-7 days on the 12th of june I went for my yearly exam everything came back fine, my iron was low so I begun taking iron pills. I had protected sex on the 17th of june. I also had protected sex on the 19th but the condom came off inside of me so we stopped and this was before he ejaculated any. On the 26th of june I had sex we started with a condom but he did remove it, and he did pull out. I started a new job on the 29th. I did not get my period the month of july and I am very worried, there has been some changes in my life like my new job, someone moving into my house around the first of july, I also have a four year old that started going to summer camp when I go to work. at first I did not worry but I have started stressing about this and I know that can also affect it. I have not taken any pregnancy tests, I also have not had any symptons of my period starting. Im getting ready to start back school, I still have not gotten my period and it is august 2. I am 22 years old I have never been on birth control I was just wondering does anyone have any suggestions???
