Hi,
Welcome to HCM,
Thanks for posting your query to this forum,
Your symptoms of nausea and headache could be result of withdrawal of
oral pills but usually they are mild and disappear with time.
The other possibility is migrainous headache which can be accompanied by nausea and vomiting.
If you are gluten sensitive then you need to go for test and if found positive you will be put on
gluten free diet ,there is no point in presuming that you are gluten sensitive and avoiding food items unnecessarily.
Please visit your Physician and this can be treated according to cause with
analgesic and anti emetics.
If
migraine is there and frequent then some preventive therapy may also be given.
It takes 4 to 6 week to resume your period but if you do not get one take a urine
pregnancy test and further action depends on result.
Hope this information helps you.
Take care.
Good Luck.
Dr.Akhilesh Dubey M.D.
