I'm sorry to hear about your abortion
A regular cycle usually indicates that the egg has released in that cycle although no-egg-release can occur even in normally cycling women.
However, the probability remains that there may not be enough inner hormones available to support an early pregnancy
and if not provided from 'outside' in form of pills or injections may result in loss of pregnancy.
I mention this because this month your period was delayed. Delayed period means either no egg release or less hormones available to cause period at correct time.
So you see, your miscarriage
last year and your delayed period now may be connected.
This delayed period could have 2 more reasons- pregnancy which you have ruled out; and an oncoming menopause
known as peri-menopause. For the latter a blood level of FSH on day 2 or 3 of the cycle can help to find out if you are moving towards menopause.
I would like to point out that the average age at menopause is around 47.6 years in India and 51 years in western countries.
Don't lose hope, however. If you have an intense desire for pregnancy despite your age, delayed periods history or a perimenopausal status on FSH, you should visit a IVF specialist in your area.
