As with all treatments, there are potential risks and negative side effects.
It is important to note that chemical menopause IS a temporary menopausal state, and although your mood symptoms will hopefully improve until/unless you have adequate steady estrogen therapy, you likely will experience some of the unpleasant physical symptoms of menopause (a state of low estrogen) which may include: night sweats, hot flashes, joint aches, fatigue, headaches, dry/itchy skin, low libido, vaginal dryness, insomnia, nausea, heart palpitations, urinary frequency. Also, you are likely to have emotional/cognitive symptoms such as anxiety, low mood, brain fog, and forgetfulness.
It is also possible in some cases that your mood symptoms may worsen initially until adequate estrogen therapy is used.
If you have questions or concerns - do speak to your provider.
