ok so I've been getting headaches every day around the same time. this has been going on for about 2 weeks. I just had my baby 4 months ago. I've tried taking something for it but it doesn't always work. and it's always right before I need to take my birth control pill. so my question is what can I do to help this go away. I would like to not go to the doctor just because of headaches.
