Stupid question- is decaf coffee unsafe for TTC and pregnancy

Soooo I know everyone is rolling their eyes, but hear me out.

My mother sent me a book on nutrition during pregnancy, and it’s pretty “out there” if you know what I’m saying, my mom is a huge health nut.

This book said that coffee, whether or not it’s decaf or regular, can cause issues TTC and with the baby due to “toxins”... so I googled it and there’s some very small studies showing a correlation between decaf coffee use and MC.

I LOVE coffee, I switched to two cups of decaf a day while TTC instead of full caff, and last month I had an early MC at 4 weeks.

I know they’re probably unrelated but now I’m in my TWW and all I can think is that my decaf is going to hurt my chances 😭🥺 help!! Did you drink coffee (regular or decaf) during your TTC journey and pregnancy? I need reassurance.
