Im now 14w and 1day and ever since I turned 11w my migraines have turned into cluster headaches and I.cant function. Ive even lost my.job. the second I lift my head off my pillow I throw up everywhere the pounding is unreal. My doctor told me to drink water and take Tylenol but THATS EXACTLY WHAT IVE BEEN DOING. The doctor told me I could take Excedrin that it might outweigh the consequences but does anybody have any tips advice on how to stop these headaches I can't take it anymore I've lost 17 pounds since I got pregnant and I now weigh 124. I mean I know the baby's getting proper nutrition but I cant live like this
