Gone off food? (5 weeks)

So, I have been feeling fairly apathetic about eating for the last few weeks (unusual for me, I assure you) and every time I do eat, I end up feeling bloated and uncomfortable.

I thought I just had a tummy bug or something, but I was a week late for my period, so I took a test, just to be sure. It came back positive, as did two others

It's a bit of a surprise, but we're excited. (my partner and I were not, not trying, if that makes sense?)

Anyway, should I be concerned about my sudden lack of interest in eating? Is this normal? How did y'all deal with appetite oddities early on?
