Pregnant vs Wishful thinking

This is our first month TTC. I have super long irregular cycles, but best I can gather they are 35-36 days long. Now I am about 4 days post my (supposed) ovulation and I am breaking out like a teenager. I also have back/stomach cramps but this is likely due to my new workout regimen and subsequent soreness. Did anyone else have acne as their first sign of pregnancy?
