New; low goal. Need people to talk to!

Hi everyone!

I have been using the MFP app on my phone for ages, and only just realised I can have friends on there for encouragement! I am friends with MeepTreats who is great, but I want more advice!

I am 128lbs, 5'4, walk 40 minutes a day about 3 times a week, and have set myself a daily calorie goal of 1370. It was 1200, but then I realised it was too low after calculating BMR and TDEE.

I think I'm doing ok. I keep to my goal, and I am starting to go for a 1 mile run every other day (only twice so far). I am getting married on september 7th and want to lose 8lbs so that my dress isn't too tight. It fits ok at the moment but I could really do with losing these lbs.

Do you guys think it's achievable in 5 weeks? Thanks!
