Feeling huge

Lauren
This is my second pregnancy and I literally feel huge. I am 20 weeks tomorrow and I feel like I'm 7 months. I was super tiny with my daughter until around 7 months. I'm also feeling the baby move ALL THE TIME and I'm starting to think I might be further along than I thought. Is this normal for a second pregnancy? I have my full anatomy scan on Wednesday but I was wondering if anyone else has experienced the same.
