Respected Doctors, I am 29 years and my husband age 45 years. We married almost 9 years and have 2 sons 7 year 8 months and 3 year 4 months age. My husband did not like to use condoms so last month me done copper. After that last few weeks we did lots of intercourse and every time husband discharge sperm inside my vagina, but my last period start some days late. So after copper is there any chance of pregnancy? Also want to know as my husband want to intercourse most of days in a week but as we have big age difference how many days intercourse good for us?
