hi, I am 28 years old, unmarried. I got chicken pox last month i.e., 10th July. My last periods was on the 5th of July, 2015. This month I did not get my periods. My menstural starting dates: March - 5th April - 3rd may - 6th June - 7th July - 5th Can chicken pox delay my periods? I got rashes even in my genital parts too. In the month of March, my fiancee just touched my vagina with his hand and I gave him a hand job but we did not have intercourse. Is it possible to be pregnant from that? That was the first and last time we did that. Since then nothing as we got scared of the possible consequences. I took urine pregnancy tests a week before and today also. They are negative. Kindly tell me why my periods is delayed?
