Hi,
Welcome to ehealthforum.
The midcycle bleeding could be suggestive of possible ovulation bleeding, breakthrough bleeding, hormonal imbalances etc. The exact cause can only be made out after careful evaluation. Consider visiting your doctor/gynecologist for thorough examination and further evaluation to look for the underlying cause for the abnormal bleeding that you describe. Treatment as indicated (based on examination findings and investigations results) would be started to help you regulate your periods. Consider being in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
