Ay, welcome sa implant club! Honest answer: ang weight gain/loss really depends sa tao, a few of us tried it, and some gained a bit (like 2-3 kilos) while iba naman walang changes sa weight at all. The most common thing I've heard from mums around me is the period situation, either super light, totally gone, or randomly spotting, plus some had breakouts; one friend in my mum group swears the acne cleared up after three months though, so it can settle down. Most mums I know say the convenience makes up for it, pero definitely worth discussing the full list of side effects with your OB first para ma-address mo lahat ng concerns specific sa'yo. Good luck with your appointment!
