Is it normal to have swollen and tender breasts after diagnostic laparoscopy?

I had my surgery yesterday and I noticed this afternoon, almost exactly 24 hours later that my breasts seems a little bigger. I’m not very well endowed so any change in size is very noticable. My period is due next week and that usually makes my breasts swell a tiny bit but they have never gotten as big as they are today.

Do you think it could be hormonal or a reaction to the medication they gave me? If anyone experienced this, did your breasts return to their regular size or is this a permanent change?
