Aa

Hi everyone being trying to conceive for over a year now so I Decided to get Blood Test done private as my doctor don’t pass much heed of the blood results I got done of my own doctor they said everything was fine just folic acid low a bit noting to worry about just take a tablet.

So my private doctor done my bloods and it came back that my Iron is so low there giving me iron Injections also my B12 is very low getting injections for this as well and my floic acids is also low.

I guess my question has Anyone found it hard to get pregnant When these where low or could this be my problem
