I am 6 weeks pregnant. Started folic acid as soon as I found out when missed period at 4 weeks. I wrongly thought he neural tube was open till 12 weeks but was shocked to read it shuts around 6 weeks. I'm now worried sick about the missed weeks of takin it. We had been loosly TTC kinda not thinking about it n seein what happened n I'd been taking it on of and off but had fallen on way side. I've found out early so that's good n midwife said I will have got some from food but just can't shake the worry it's making me feel ill. Nothing I can do now n I'd like to think things are written in the stars anyway but any tips on shaking the worry most welcome! My first child I didnt find out till I was six weeks gone n started it then he was just fine x
