Miserable

I'm 34 weeks, for the last 5 days I've had a horrible. Paged dr Tuesday night n he said to take Tylenol n Benadryl and call on Wednesday morning if no better, Seen dr yesterday, sent me to the new life unit to b monitored. Yes my blood pressure has been fluctuating! So they gave me Tylenol n Benadryl then sent me home. Woke up this morning with no change, headache is still as bad! Has anyone else had this problem? Please help I'm beyond miserable!!!
