Also, not a dua per se, but try to read surah mariyam, in English if you don’t understand Arabic. The first few ayat are about the Prophet Zakariya AS and his supplication to Allah for a child. He was v old and his wife was barren but he asked Allah anyway and he was granted the prophet Yahya AS who was a blessed and obedient child. Really beautiful read and gave me so much hope when I was TTC.
The supplication of Ibrahim AS - ‘Rabbi habli minas saliheen’ Translation - My Lord grant me a child from amongst the righteous.
Have you tried reading salat ul Haja? I find that works for me always, especially when I’m feeling desperate. I also tend to read tahajjud and salat ul Haja around the same time (before Fajr).
One more 🙈…not for TTC but surah Duha is really good to recite if you might be suffering from anxiety or feeling down. It’s a reminder that Allah has not forsaken us, nor has He forgotten us. Again in English to fully understand the meaning ❤️
