Hi barbie86,
Welcome to the Migraine.com discussion forum - we're happy you found us! Let me see what information I can give you to help.
Migraine can be depressing, stressful, exhausting and frustrating, but you're not alone! There are over 37 million American's that have migraine, and its helpful to connect with others who understand the impact migraine can have on one's life.
While its true some women experience an increase in migraine frequency, others feel better which may be due to the influx of hormones. I don't have migraine with aura, but can tell you I did have an increase in my migraines during my third trimesters. Let me give you information on migraine and pregnancy in this article; https://migraine.com/blog/migraine-pregnancy-expect/. We also have an entire section devoted to women and migraine you can find here; https://migraine.com/living-with-migraine/hormonal-migraine-the-basics/.
Migraine with aura can increase our risk of stroke. We do have a number of articles on this topic which will help; https://migraine.com/blog/stroke-migraine-with-aura-prevention/ and https://migraine.com/blog/migraine-aura-medication-stroke-assessing-risk/.
Migraine is thought to be a genetic neurological disorder and may be triggered by many things such as certain foods, changes in the barometric pressure, dehydration, irregular sleeping patterns and many other things. It's not that oral contraception is 'caused' by migraine, but it may trigger them. During pregnancy it's a good idea to have your OB/GYN and neurologist on the same treatment page.
Let me know how you make out,
Nancy
