What was the benefit if they were going to experience the same symptoms. Does it say how many, percentage wise. Received first dose in Aug. One month post dose (Sep, middle) longer, heavier menstrual cycle. Oct still waiting. She does not know if she was going to fall into that category. Blood pressure previously in Jun 112, went in 130s. Maybe the stress of the vaccine because she does not normally get vaccines. She always worry about stuff like this. She felt a little pressured.
