This is very unlike me - I've been taking folic acid for more than eighteen months, currently having fertility investigations due to my age and other health conditions. I've never forgotten a single tablet this whole time.My period started the other day and I was in so much pain I couldn't eat in the evening, so I didn't take my folic acid. The next day, it completely slipped my mind again. Will this make a difference considering I've bene taking it so long previously? I hate thinking I had this uninterrupted streak for so long and then messed it up! Psychologically it feels like I'm starting again, I know this is probably irrational.
