Hello sir/madam, I had intercourse on 27th November and my Last period date was 17th November. We had an unprotected sex as we tried pulling out that time. Because of lack of knowledge, we thought it can't make me pregnant, but on 2nd December I started discharging and it turned to white discharge and excessive. From 4th December I am seeking sour foods. But still white-discharging, and somehow I am feeling more interested in having sex. Is all that any kind of sign of pregnancy ?
