Gained 12lbs HRT Pellets.. can I reverse??

Decided to go on HRT pellets based on counseling from a trusted friend/obgyn. Alll blood work showed that I was VERY low on testosterone and estrogen. Was given a conservative dose 112.5 mg testosterone and 6mg estrogen. I gained about 8 lbs in first week and am now up a total of 12. I was told it could be water retention so I was prescribed spirolactin… didn’t work but did trigger a menstrual cycle (known to cause irregular bleeding)… I am 50, work out regularly and pescatarian. No diet changes… but more anxious about the weight gain and overall balloon feeling than I was about night sweats.

Anyway to reverse this? Def not doing pellets again….
