Hello Doctor, I am planning for baby from last 3 months, still I am not get pregnant. My last period date was 23rd June, still my period dint come. We took Home pregnancy test it's negative. Should I need to wait for few days?. Or shall I need to consult regarding missed period and check up. As I am lot of stress related work, there is no proper sleep and exercise is that causing delayed period?. I have mood Swing and not getting interst for the sex. Kindly suggest for further medication and check up.
