I agree with above ! because many a times a woman conceive despite having all odds & some woman do not conceive despite having everything in their favour. A child brings his/her own naseeb and he/she cannot come into this world without the will of Allah. Date & time of birth & death along with many other things are decided by Allah and are simply not in our hands.
but i just want to add something in your last para …it’s not about understanding your inlaws and husband you understand them or dont that doesn’t matter , its about they understanding you. during pregnancy a woman needs support , only who have been thru it knows how bad it can get at times and if ur inlaws & husband doesn’t support thing can become very hard . so it’s about ur husband & inlaws understanding you. a bahu is a like a ball in their court they may kick her and throw her away anywhere and anyway they want.
