Hi, I guess your concern is about reasons for not getting pregnant, right. Firstly I want to tell you that there many reasons or factors which are responsible for not getting pregnancy. These factors can be present in wife or in husband or in both. In most few cases reasons are unknown.in case of female most common reason is ovarian factors like - irregular menses, cystic ovaries etc.tubal factors like blockage of one or both fallopian tubes, uterine factors like fibroid etc. Sometimes there is a hormonal causes like abnormal thyroid hormones, excessive secretion of prolactin hormone etc In case of male most common factor is abnormality in sperm or sperm production etc. Secondly let us discuss about your problem: - as you told that I missed your period for 2 month but pregnancy test was negative and you are having pain, white spot around nipple and on squeezing there is discharge from nipple,right. This problems mostly occurs in case of high prolactin level in the body. It is milk producing hormone which is secreted from pituitary gland. When it s level is high in body, it causes irregular menses and milky discharge from the nipple etc. But you have not given information regarding your menses whether it is regular earlier or irregular from the starting and also you have not told about the character of the nipple discharge. So it is difficult for me to comment on this. With above discussion you can try out my suggestions- 1. As you told that you are taking birth control pills. This pills are given for regularization of menses. Once your menses will regular, there is high chances of getting pregnant. So DON T WORRY. 2. Try to do coitus in fertile period (it starts from 10th-16th day of menses) during this period chances of getting pregnant is high). So do coitus as more as possible. 3. If you are in hurry then visit nearby infertility specialist. He/ she can help you. I hope the above information is useful, informative and helpful. Let me know if I can assist you further.
