No baby for the next five years.. 😕

During my last check up, my breast surgeon interpret the latest laboratory test done. It was the P63 and estrogen and progesterone.
I may not fully understand the medical explanation for this but what matters to most is that I don't need to go trough chemotheraphy or radiation as if now as the test results confirmed that it was not invasive.
But then there's a probability that it would recur anytime. So I need to take Tamoxifen for five years.
There are various side effects of taking Tamoxifen that's why the doctor instructed me to try various brands so I would know which will best suit me. Some of the side effects mentioned was almost same as menopausal syndrome. There will be times mentruation will stop, some sort of moodiness, restlessness, and dizziness. But at times, these do not happen.
The worst of this is that we are not allowed to have additional baby for the next five years. The medicine will cause deficiency in case I'll get pregnant. We are the prime age yet young couple. We only have one son as if now and not sure if still capable of bearing after five years. Anyway, again I know He has plans for us...for me..whatever it is...I'll just hold on...and go on with my life.
