bloating help

I'm currently about 6 weeks pregnant and bloated so bad. It's so hard to stay comfortable in my works clothes (I'm a teacher) I need something to get me through until the end of the year and I don't want to buy new clothes yet has anyone has success with any belly bad or any product like that in order to feel comfortable during this time. I have done the hair tie trick a few times but I feel like you can see it, just looking for ideas of how to hide this easier without buying all new clothes. Thanks in advance!
