Hello,
Thanks for posting your query at DoctorSpring.com
From what I gather, you are still on the birth control, and should not have had any period at all, right ?
SO you are having breakthrough bleeding.
How long have you been taking these pills, and can you elaborate on how long you have been taking them this time without the pill free period ?
Another thing - most of the medications you mention, can interact with the pill and cause irregular cycles.
You would need an internal exam by an OB - GYN, a Pap smear and a pelvic ultrasound scan in addition to regular blood work.
A fibroid, polyp, cervical lesion, ovarian cyst - need to be ruled out.
All the best
Please feel free to discuss further.
Regards.
