hi ! menstrual troubles are now a days commonly seen in 9 out of 10 women in one or the other degrees, some have very much excess bleeding, some have very scanty bleeding. though excess or scanty flow is abnormal factor, but it is not the deciding factor for pregnancy. pregnancy depends on menstrual cycle and more precisely on ovulation. if your cycles are regular be it be with excess or scanty flow, it means that your hormones are functioning nrmly and there is very much chance for pregnancy. if you want get it confirmed then you need to go for FOLLICULAR TEST, where you will be tested to know the status of your follicle and its condition its size etc,etc during ovulation which is generally done on 14th -16thday with a cycle of 28days. so you need not worry about your scanty discharge, there are many other reasons for scanty flow like aneamia etc,etc. just proceed for pregnancy if you have no other issues in health.

If you are having irregular menses and if you are over weight get your ultrasound pelvis done to rule out any ovarian cysts get it done on 3-4 day of your periods.

Hello there. I can understand your concern. There is no way we can say what is wrong with you with just this much information. A detailed history, clinical examination and a battery of tests will be required to know what's wrong with you and why aren't you able to concieve. Consult a infertility expert in person for further evaluation and management. You should also take your husband along with you and get him also Checked out. Best regards. Dr. Anil Kumar Jain.
