I accidentally got depo provera on my skin, needing advice.

So i work at a OBGYN office, i was drawing up a Depo Provera shot and a had little of it squirt on to my cheek on my face, as soon as this happen i got a wet paper towel to get it off my cheek. im worried it will make it harder to get pregnant or mess my cycle up. weve been ttc for a year now. Also, nurse practioner said dont worry about it. what do you think?
