How much protein is too much?

Today..

8:00am - prawn omelette
10:00am - home ab workout
10:30am - protein shake
12:00pm - cheese strips and some natural yoghurt
2:30pm - pack of Bernard Matthews turkey
4:00pm - gym - social cardio (walking on the treadmill and steppers) and a weighted leg routine
5:00pm - lettuce wraps with turkey, salsa, guacamole e.t.c

I was thinking of making some protein pancakes for a late night snack because I'm peckish but then just realised I've had a lot of protein.. I'm trying to get a lot anyway (137g I was told) but I'm on 148g ... Obviously this amount is different today.. I got stuck with lunch and afternoon snack due to a family emergency and cheese, yoghurt and turkey was all that was available... But is it dangerous to go and have protein pancakes when I've had so much protein today?

Please don't laugh I'm not the wisest fitness person out there (:
