Night sweating 3-4 weeks post op from liposuction. Is this normal?

I had liposuction (inner and outer thighs) 31 days ago. I usually have 1-2 nights of night sweats the day before & first day of my period. Last week I had my first period since surgery, & have had night sweats ever since. I have an appt to see a general doc next week, but starting to worry. Is this normal? I am going on 8 days w/ sweating at night, & I am concerned. Especially because I am now a month post op. I am 28 years old, so not going through menopause. I am 5'4" & 128 lbs (post op).
