HI, Thanks for your query. I do understand your concern.  I am sorry for the loss of pregnancy you had 3 years back. Most of the time cause of pregnancy loss is pregnancy abnormality/ viral fevers in mother/ fall with trauma to abdomen. So once abnormal need not be same again Please don't worry.  Now after so many days, we can think of repeat possibility after blood tests (Thyroid function tests, V Chat Doctor.  * The 5 months lack of menses you had can be hormonal imbalance immediately after delivery/of due to certain conditions like POD afterwords.  * I think irregularity of period you have is the cause of non conception in your case. So You need a gynecologists advise/ investigations ( HBO to assess your general condition/ USG abdomen/thyroid function tests/ hormonal estimation & after knowing the exact cause, you would be given specific treatment. So as you start having normal menses with ovulation.  - At the same time some weakness in semen ACN also be the cause. Which needs to be excluded/ treated with doctors advise.  - Psychological trauma due to lost pregnancy, fear & anxiety can lead to hormonal imbalance/ irregular periods & lack of. So you should discuss the thing & your doubts with your doctor, get a clear concept & be free from any tension... this will help conception.  Thanks.
