I am 24 years old. I wanted to know can unprotected sex lead to pregnancy if no ejaculation happens inside vagina? I was into this for around 7 days, about for 10 minutes each day. I am having severe vaginal irritation now for which Lybrate doctors prescribed with metrogyl 400 and Clingen vaginal insertion tablets. I am under these medication. I am not having my periods. It is 5 days late now and still counting. I am detected with PCOD and often get delayed periods. Can there be any pregnancy related issue? Please respond. I am very worried.
