Showing earlier in second pregnancy after mc?

Lauren

I miscarried in April at 11.5 weeks. I'm not 5.5 weeks along with number two and swear I look 4 months pregnant. My stomach is hard as a rock and with my morning (all day 😞) sickness, I'm not even eating half of what I used to. Just wondering if my uterus would have expanded enough to cause me to show this early. Stressing because I'm trying to hide it 5-6 more weeks.
