Many thanks for your question.
Taking a mixture of the three different contraceptive injections, being Nur-Isterate, Depo Provera and Petogen (which is the generic for Depo Provera) over an eleven month time span will most definitely upset your hormonal and menstrual cycle. Why were you taking three different contraceptive injections in the space of three months?
Your body will attempt to rectify itself on its own. However, having had a miscarriage as well, will also have affected your hormonal equilibrium.
I suggest that you give yourself time and add loads of patience while your body rectifies itself hormonally. Do give yourself another three to six months, and during this waiting time, I recommend that you take the following :
Take CHASTEBERRY PLUS by Metagenics, as x1 capsule, 3 times a day after food. This product will assist in regulating your hormonal cycle, and promoting reproductive health. This is a natural product and has other ingredients like Black Cohosh, and Ashwagandha for increasing a better sense of well being, promoting women's health and a healthy libido. Continue with this product until your menstrual cycle returns.
At the same time, commence taking the following two products for three months please :
CELA-PREG by Arctic, as x1 tablet after breakfast every morning. This is an excellent multivitamin formulated for women trying to fall pregnant; for during pregnancy; and for 3 months after pregnancy. It is an excellent source of iron where a mother is iron deficient and suffers from a malabsorption of iron.
MUM OMEGA by Equazen, as x1 capsule at night, about an hour or so after food. Taking a good omega supplement is essential to promote a healthy baby's brain tissue, nervous system, and musculosceletial system.
Please follow the above advise as given, and this should greatly assist you in achieving your dream of having a baby!
I wish you all the luck in the world! Please let me know how you do and when it finally happens.
