Bad week and now full of guilt

I am 8 weeks pregnant after 18months of trying with PCOS. We finally conceived after 4 months of pretty clean eating, low sugar, no alcohol, minimal caffine etc.

Trouble is I now have pretty bad nausea and all I am wanting is carbs so all the clean eating has pretty much gone out of the window. Coupled with a couple of days of pre-Christmas cakes and biscuits at work.

Now I’m not feeling so sick but I am now full of guilt I may have harmed the baby??? And I’m just constantly anxious about miscarrying 😥.

Will a bad week have a big impact? Thank you
