Lip tie?

Melanie
I'm really going someone can help me out... My baby girl is 3 weeks 5 days old and is strictly breastfed. For the past two weeks she has had gas and has been really colicky. My doctor suggested I cut out dairy and spicy foods and we have but she still seems fussy. I noticed the last two days she began puking away as she feeds and screams and then goes back to feeding... She seems to be doing that roughly 4-5 times per feeding. I did alot of research and some people mentioned lip ties so I took a peek and to me it looks like she may have one?! Can anyone give me some insight on this and advise... Does this need to be fixed? Should it already have been fixed? I'm really upset about this and her next appointment isn't for another month! I just don't want her to have to be in any type of pain and definitely don't want to wait of it needs to be fixed... Help!!!!
