swollen ankles

I'm 36 weeks pregnant and I just cooked dinner nothing big just spaghetti and I was wondering if it was normal for your ankles to swell just from standing and cooking. My feet aren't swollen and my ankles aren't bad just enough to notice and I feel like I have so much weight on me. I'm a FTM so I wasn't sure if that's something I should be seen about or if it's normal TIA
