Taking a break (pregnant)?

So, found out Monday I'm pregnant (thanks Keto!). The question now, though, is whether to try and stay Keto. I've been failing miserably so far because any thought of meat turns my stomach and all I've been wanting to eat is salads, fruit, and breads. Luckily sugar/sweet things turn me off horribly. So, should I try to ignore my cravings and try to stick my best to keto, or take a break until the baby is born? Thanks for your advice!
