I'm 19 years old (female) and I had sex for the first time. We used a condom, I should be getting my period in about a week. I just don't want to freak out when I don't get my period. So, I'm wondering, because it was my first time, could my body delay my period?
Stress is the biggest cause of a missed or delayed period. The stressor is the worry you may miss your period because you are pregnant. This is a common worry for all women especially young teenager, virgins and those that have unprotected sex. The other factors that could cause a missed period are medications; both prescription and over the counter medications.
If you have taken any type of medication or have been stressing about this since you have had sex, it could cause a delayed or missed period. Don't freak out and jump off the deep end thinking your pregnant. You go and get a home test kit and take a test. If it is negative then relax. If it is positive wait a week and if you still don't get your period test again. There are more false positives than false negatives in the home test kits.
Condoms are 85% effective in preventing pregnancy. Depending on where in your cycle you ovulate also determines when you are most fertile. For most women it is a period of time somewhere in the mid two weeks of a 28 day cycle.
At 19 you are an adult now responsible for your own medical well being and entitled to a sex life should you wish to have one. Since you have had sex I would suggest you visit your GYN and discuss a birth control medication that is proper for you.
Birth control pills are 99% effective in preventing pregnancy. Birth control pills and condoms used together are close to 100% effective. When having sex you should insist the man use a condom as a condom is also effective in preventing the transfer of some but not all of the STDS and HIV/AIDS.
