Should I worry?

Heather

So my daughter will be 4 months old on Friday. She also has an appointment that day for her 4 month shots. However, she's been extra fussy the last couple days. Last night she wouldn't sleep unless I was holding her. I nurse her to sleep and wait about 20-30 mins before I know she's really out and then lay her down. Usually that works but last night anytime I layed her down she woke up instantly and started crying. Today she feels a bit warmer than usual. I took her temperature and it's at 99.2. I guess I'm just wondering if her temp is okay and any advice you ladies might have. T.I.A!
