Are there any chances of getting pregnant having Unprotected Sex 2-3 days prior mensus date? We have had two more times this month but using precautions. My cycle is 5 days delayed and i am having pain in lower abdomen and yesterday I was finding fish smell very much disturbing for first time. I am not sure if these are the positive signs or I am over thinking and assuming stuffs. Rarely I do have my cycle 5-10 days up or down but this time i have few signs.. Please guide me.
