Anyone still losing weight?

I'm not sure how much I should be gaining, but I'm pretty sure I shouldn't be losing weight..

17w1d

I haven't had real sickness in my first trimester, I am still recovering from a stomach bug.

So I started my ttc journey at 80kg, which lasted about 2 years, but I was about 78 kg when I conceived and now, over 4 months, I'm weighing 76 kg.. For 1m67...

I know I'm not skinny, but is it healthy for me to be losing weight?

Or is it not significant enough to be a problem?
