So I bought my breast pump today. Tried it out and now I have weird pains in my belly and a dull lower back pain. I called my aunt and told her what I did and she told me that it was bad because it can cause me to go into early labor and now I'm kinda freaking out 😔😔 I'm new at all this but I feel so stupid
