Infertility in Marriage

Infertility in Marriage

Why is it in our culture when the blessing delays it's always the woman's fault?Why is it the woman's responsibility to seek for all possible help to conceive?

Before we got blessed with a child I remember Patrick's sisters sending emails on how to position legs ☝️ after the deed is done so that I can conceive.The other one asked me to be in good books with my partenal grandparents so that I can conceive

On the other hand Patrick had threatened to go have a baby outside wedlock to prove that he can impregnate a woman  

Mind you,I had not even been diagnosed of infertility at that time . After several fertility treatments and procedures such as HSG,I eventually got pregnant in my 3rd year of marriage.Unfortunately my ex husband started having dreams that the baby was not his,wanted an amniocentesis to which I refused and he took the baby to the DNAS 6 weeks after birth.

I had never given him a reason to assume that I am cheating but he just had to.It was so much to take in.

Back to my question

Is it culture?If it's not culture then what is it that causes women to be blamed if there is no child blessings in the marriage?
