First portable pump?

Hello,

I’m 6 weeks postpartum and unfortunately an undersupplier. I’ve been using my blue Spectra for pumping to try to increase my supply. Meanwhile, I’d like to buy a portable/mobile pump that can be tucked into a bra so I can be more free.

Are there any mobile pumps you recommend that could help me continue to build my supply? (I don’t mind the price of the pump and am willing to pay whatever it costs.)

I read about Willow Go, Elvie Stride and Elvie OG, which all seem to have their pros and cons. I read on here that someone’s lactation consultant said Willow causes nipple damage so I’m a little wary of that brand. Ideally, I would like a mobile pump on the smaller side and doesn’t easily leak.

Do you have any recommendations?

Thanks in advance
