Q: If you have a one night stand, what should you check for the following days?
A: One-night stands, hookups and casual sex in general can be a relatively safe experience as long as you prepare a bit in advance. Obviously, it's always best to have condoms on you, in case something like this happens. If you're a woman, I also suggest being on a long-acting reversible form of birth control, such as birth control implants, which are very safe and effective can be attained at Planned Parenthood. Also, it's not a good idea to be really intoxicated if you're going to hook up with someone, because then it's likely you'll be far more reckless, such as not using condoms or having sex in a way that you're not comfortable with.
Let's assume that you didn't totally prepare and perhaps you didn't use any safe-sex practices. In that case, if you're a woman and you don't want to get pregnant, I would strongly urge you to take "Plan B" or some other type of post-sex birth control. Plan B can be purchased at regular drug stores, such as CVS or Rite Aid. It's a bit expensive (around $50), but it's well worth it if you didn't use any form of birth control. This medication basically causes you to quickly begin menstruation, flushing away a potentially fertilized egg. This can cause you to experience some pretty bad cramping and a heavy flow, but that's to be expected.
If you're worried about STIs, I suggest going to Planned Parenthood to get a full STI screening. You can visit the Planned Parenthood in Merced at 3166 Collins Dr, Merced, CA 95348. You can get an STI screening for free and, even if you're on your parent's insurance, you can let Planned Parenthood know not to bill your insurance, so that your parents won't find out. There are some STIs that take a while after being infected to show up in a screening test, particularly HIV. Sometimes, HIV won't show up in a screening until 6 months after someone has been infected. So I suggest getting screening a week after a one-night stand and then scheduling another appointment for 6-months later to do a follow-up.
As you can see, having a one-night stand can cause a lot of issues and require a lot of work afterward if you don't properly prepare beforehand. So, in the future, make sure you're using some type of long-acting birth-control and condoms to protect yourself from pregnancy and STIs.
