first time pregnancy - worries and concerns

Hi guys.. this is my first pregnancy and im still quite early (just over 7 weeks). I'm just looking for guidance or reassurance. I feel crazy because I find myself worried about every little thing that I am eating, soaps Im using for my face, things I can do and can't do. I guess it's because I feel responsible now.. Ive been trying to eat more fruit but I just dont fancy veg or anything healthy! im usually so healthy but all I fancy is bad food right now!! did anyone else have these concerns? its really stressing me out 😞
