I have had chronic migraines (literally one a day but some last a while some over a month) for a decade now and do get the period headaches. Cyclic hormones for birth control can make them worse as you have had the unfortune of enduring. You might talk about birth control like Seasonale, Depro Provera or IUDs for birth control with your doctor unless you are on the pill because you are planning on continuing to expand your family in the nearby future. These birth control options do mean it will take longer to have them run out of your system and extend how long it may take to get pregnant.
I joined a migraine support group which has made my life better. Not only do I have others who face the same problems at work and home because of the ailment, but I get loads of information and some ideas for home remedies to try to ease the suffering.
Sometimes drinking caffeine helps, but also you might try tea. Experiment with types of teas as different ones can help (plus you find out what you like). Peppermint tea can help by easing nausea. Chamomile has have a calming effect which can help. Lavender, vanilla, peppermint are some scents that might help with a migraine.
I use cold packs not only on my head but on my neck since it becomes intensely tight. I ask my doctor for Phenergan which helps with nausea and can also help boost the effectiveness of migraine medicines. I take supplements of Feverfew, B complex and Magnesium daily to prevent and control migraines.
Some use ICY HOT on their temples and foreheads to try to manage the pain. Other will use mentholated shampoos to try to combat a migraine. You might need abortive migraine medicine if you don't already have some.
Many of my migraine medicines as long as they were nasal sprays were allowed by my OB/GYN in pregnancy, since they were absorbed quickly in my nose and less likely to go through the blood stream and to the baby. I was also allowed to use Maxalt MLT and Zomig that dissolved under my tongue.
Having a regular sleep schedule and exercise program have been beneficial to many sufferers.
It is important to call your doctor if your migraines lasts for over 72 hours. Your run the risk of stroke, heart attack, and sometimes even death once it goes beyond 72 hours.
Some people have luck with taking some Benedryal and Naproxen Sodium (Aleeve) as migraine abortives.
Unfortunately, at times it can be a long bunch of trail and error to find a solution that works best for you.
I hope you can get the relief you need so you can better enjoy the time with your kids.
