Severe Cramps, Disruption In Normal Menstrual Cycle, On Birth Control Pills, Negative Pregnancy Test. Cause?
Your question is a very good one and I will work on providing you with some good information and recommendations regarding what is going on.
What you have described certainly does reflect a moderate degree of hormonal imbalance. When this occurs it can lead to a disruption in the normal menstrual cycle. There are a number of factors which also could contribute to this including a fluctuation in weight as well as a fluctuation in daily stress level.
I agree that starting a new birth control pack was appropriate to management. It may take 6 to 8 weeks before your body is adjusted back onto a normal cycle. The irregular bleeding such as you have reported is not uncommon. I would encourage you to continue taking this medication as prescribed on a daily basis. If you feel you're losing and excessive amount of blood or if you are using a significant more than usual amount of Maxi pads or tampons you should touch base with your physician.
As your hormonal balance comes closer to harmony you will likely experiencing normal cycle within the next 4 to 6 weeks. I know it is difficult to tolerate in the meantime but let me reassure you that things will be fine.
Again I thank you for submitting your question. I hope you found my response to be helpful informative and reassuring. If you have any additional concerns I would be happy to address them.
Sincerely,
Dr. Robert.
