What Are The Possible Birth Control Measures After A Unprotected Intercourse?

Me and my girlfriend had sex but I didn't ejaculate inside of her, but my sperm was on her vagina(during her period). Later that night, she wiped to check if sperm was on her vagina, and she realized that when wiping in an upward motion, she wiped the sperm all on her vagina. Is there any chance of her getting pregnant? If so, then how do I prevent fertilization? It's only been two days since the incidence.

Hello and welcome,

If the incident occurred when she was having her periods then there is no need for an added precaution as the chances of pregnancy are zero.

However I would like to say that in case an emergency unexpected intercourse occurs in future then she can take the emergency contraception [ levonorgestrel tablet] sold as Ipill or plan B one step within 72 hours of contact and it is effective in more than 95% cases if used correctly. However it must be used only as an emergency measure, not more than once in one cycle and if the contacts are repeated use of other measures like condoms [ also prevent sexually transmitted diseases] or oral contraceptive pills, injections or implants [ after prescription from a doctor ] are advisable.

Hope this satisfies your query.
Thanks for using HCM.
