###Human: Will I get pregnant after having unprotected sex the night before I got my period? ###Assistant: Hello. No, you are not pregnant possibly, because having sex just right before periods does not result in pregnancy. Secondly, if someone gets pregnant even then the symptoms of pregnancy does not show up quickly (15 days after having sex). You might be having stress and anxiety which is causing all these symptoms. You need to relax now and wait for your next periods to start. Hope it has helped you. If you have any further queries, please do not hesitate to contact me.
