Hi doctor I got a triclofem injection for three...

Triclofem injection:
Triclofem is used for long-term contraception in women which contains Medroxyprogesterone acetate.

Pregnacare Tablet:
It's a dietary supplement that provides nutritional support to the mother and the baby during pregnancy. It is composed of essential vitamins and minerals that aid in the growth and development of the unborn baby.

How long does it take for fertility to return after injection?
It can take up to 1 year for your fertility to return to normal after the injection wears off, so it may not be suitable if you want to have a baby in the near future. 

Is it hard to get pregnant after the injection?
It's unlikely that you'll be able to get pregnant right after you stop taking the shot. Because each shot delivers enough hormones to protect against pregnancy for three months at a time, the earliest you may be able to conceive is about 12 weeks after your last injection.

Recommendation:
It's recommended to follow up with your GP.

What should you do after stopping birth control?
After stopping birth control, it's recommended to start to support your body with the diet, lifestyle, and supplement recommendations. Eating plenty of foods that has high in calcium also is strongly recommended, since the use of birth control can also thin the bones. The food includes spinach, broccoli, sesame seeds, seaweed, chia seeds and cottage cheese. The purpose is to restore the ovulation process and improve hormonal balance.

Note:
There is no medication to balance the hormones in your case.
