I and my gf had protected sex with condom on 5th sep. He was on her 6th day of period. She has 28/30 days menstrual cycle. While doing sex condom did not break and no semen come out of the condom. As per this she should ovulate on 15 or 16 September but she is not noticing any cervical mucus. It means he has become pregnant? If not what can be the cause of no cervical mucus during her mid term of menstrual cycle. She is very worried now. She is thinking she has become pregnant. No cervical mucus means she is pregnant?
