Hi,
Welcome to the ehealthforum. I am glad to help you out. Menstrual irregularities are known side effects of depo provera. This can be in the form of excessive bleeding. You need to avoid it as this could be the culprit in causing these problems.
You need to consult a gynaecologist for the same. You also need to ensure that you donât have iron/hemoglobin deficiency due to the excessive loss of blood and youâll need to take iron supplements for the same. Please do get your thyroid status also checked as variations in the same can also give rise to the menstrual irregularities. I sincerely hope that helps. Take care.
