Thanks for your question on Health Care Magic.
I can understand your concern.
You should wait for atleast 2 years from the date of your RIA treatment for
pregnancy.
After 2 years of RIA treatment, you can plan pregnancy.
Since you were on birth control pills and not having periods, possibility of
hormonal imbalance is more.
So better to first get done hormone levels to rule out hormonal imbalance.
Once your hormones are normalized and you gets your regular menstrual cycle, you can get pregnant.
So consult gynecologist and discuss all these.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
