Gaining weight already??

Cam

Before pregnancy I was about 123-125lbs. I’d weight myself at random times during the day including after eating and at the end of the day and I’ve never been past 125...maybe 126. I just weighed myself today and I’m 128. It’s seems like I’ve gained 2-3 lbs and I’m only 5 weeks. I don’t typically just gain weight that easily and I haven’t been eating any more than normal. Could it be just bloating weight or do y’all think I’m already gaining pregnancy weight?
