Any pattern to when you bleed more from injections?

The last two days, every time I inject I wind up hitting a blood gusher! This is happening both in my outer thigh for basals and in my tummy for boluses. Normally I don’t bleed at all. Have any of you had days when you bleed even though normally you don’t? If so have you noticed any kind of pattern or something else to clue you in to why it’s happening? Thanks.
