Hi, What is your age and BMI. You did not write to me whether your pregnancy test was positive when your mensus were late by two weeks. After ejaculation part of the semen coming out is normal. So don t worry. Your husband and you should consult a Gynecologist and do basic infertility investigations. Hormone tests and fallopian tube patency test for you and semen analysis for your husband. Further treatment can be planned based on the results. Take one tablet of folic acid daily. To increase your chances of conception, maintain normal BMI, quit smoking (if you are a smoker) and must have intercourse at-least three times in a week. If you have any further concerns do contact me through Healthcare Magic. I will be happy to answer.
