Should I text this girl I'm seeing Please help?

Well I've been seeing her for 2 and a half months and I was supposed to pick her up from work yesterday and today but her rota changed to nights apparently she said over a text and asked if it was ok if i popped down on Wednesday she said "I will let ya know about Wednesday cause I might be working a shift Thursday" (usually she always knows what days she is doing either working day or night) so I put back to her "ok then no problem" anyways I needed some petrol tonite so I went and got some and I have to drive past a road near her house and I drove by her street and I think I saw her living room light was on so pulled Into a little culdesack and started to turn round and I spotted a neibour nosing at me threw her window round the corner of her house now I'm scared that she might find out and think I'm a creep or somthing this was a dooche move I know and I really regret it should I text her or just wait for her to text me
