Hello, thanks for using health care magic. With an unprotected intercourse on the 6th day of menses it is less likely to beome pregnant unless in abnormal menstrual cycle or extremely short cycles. Stress is well known to delay menses and this is quite common in young girls who for fear of falling pregnant after having an unprotected intercourse develop a delay in their menses. So, to begin,, you need to first of all confirm that you are pregnant before you could think of terminating the pregnancy. Confirmation should be done with simple pregnancy testing on early morning urine and should be done after the expected day of menses. There is no natural way of terminating pregnancy. All termination of pregnancies what ever the method use are induced but for spontaneous abortions that come out on their own. Termination of pregnancy is done under strict medical monitoring and is done by a qualified personnel less you will run the risk of developing complications such as infection, excessive bleeding, uterine perforation and death as well. Termination of pregnancy is done only in Countries where it is legalized. Hope this helps you. Best regards Dr Achuo
