Help: Breast Cyst and pregnancy?

TTC for a year now and currently undergoing <a href="https://glowing.com/glow-fertility-program">IVF</a> process. Does anyone know if breast cyst will be bad for pregnancy? I found out I had a cyst in my breast two years ago and my friend is telling me that the hormonal changes in pregnancy will cause the cyst to grow or get worse so I should get checked ( mammogram or ultrasound) to see if it’s getting bigger before pregnancy. Should I be worried about that?
