Horrible headache 1-2 dpo

Kristen • Ttc#3. Currently have a 6 year old daughter and 19 month old daughter. Married to my husband may 2014.
When I woke up I had a horrible headache. I normally get migraines. I'm not sure if it's that or hormone related. I know it's too early for symptoms. What's does everyone think? Do you think it's ok to take my medication?
