Hi,
Welcome to ehealthforum,
The spotting that you describe could be due to breakthrough bleeding (which is commonly seen in women using hormonal birth control pills). Continue to take your birth control pills at scheduled time daily. If the spotting remains persistent, consider visiting your doctor/gynecologist for further evaluation to rule out any other serous underlying causes like hormonal derangements, thyroid abnormality, anemia, endometritis, ovarian cysts etc. Treatment as appropriate (based on examination findings and investigations results) would be started to help you control the spotting and regulate periods. Be 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.
