There you go. However, maybe, maybe not.

It could be due to premenstrual changes... often they will be similar to those in early pregnancy. See what happens when you expect your next period and try a pregnancy test if it doesn't show.

If you aren't pregnant, count yourself lucky and decide on a form of birth control to lessen the chances if you are going to continue to have sex. Two forms would be even better, one of which should be a condom. You have several different options available to you. Discuss it with your doctor. You could set an appointment for a general physical and discuss birth control options privately.

The withdrawal method is not very reliable as it often is not used correctly. Hence why it is on the lower end of effective methods. It takes a great deal of control and knowing your body well. One of the biggest mistakes made with it is pulling out to ejaculate and then re-entering.

Ideally you would wait on sex until you were in a position to have and raise a child, since that is a good possibility sooner or later. At the very least, be smart about what you are doing and protect yourself as best you can.
