So bloated

I feel so bloated m i know it's too early to be showing but i feel like my stomach is 10 times bigger. I haven't been eating a lot to sick i lost 2 lbs instead of gained. I tried to buy maternity bras since my boobs are also huge i was disappointed in Wal-Mart maternity section. I bought the largest nursing bra they had ands it is too small. I really do not want to spend a lot since i know I'm just going to get bigger.
