From my experience people, having a child is one of the most natural things. Our bodies are made to adjust and tolerate what we have to go through. So I say just let it be, let it come naturally and during your roughest moments, just read the 4 Quls in your head and Surah Fatiha and keep reminding yourself that millions of women have gone through this, are going through this and will go through this so I can too. InshaAllah it will be over sooner than you think because when you hold that precious baby in your hand, nothing else will matter.
