Migraines Please Help!!

Andrea
Do any of you ladies suffer from migraines and are pregnant or have suffered while pregnant? I went off all of my meds including waiting for the Botox to be out of my system to start TTC. I am now 22 weeks 4 days and on day 5 of a HORRIBLE Migraine. My specialist won't do anything and refers me to my OB my OB only gives pain meds and tells me to go to the hospital. I went to the hospital yesterday and got the Benadryl/Reglan "cocktail" which helped for a while but then it came back. 
What have you ladies done for yours? Has anyone been able to take Imitrex? I have injections still at home. 
Any suggestions are welcome so far I've been taking Floricet and now today started Percocet neither help for very long and since they are just for pain it keeps coming back.
