not getting my hopes up 🤗

Ash
So I came off of bc (IUD) on 3/15/17. We had sex three days later at the end of my fertility week. 
We've had sex a few times since then & I had the shortest, lightest period EVER - two days, 4 pads total. It's been about a week and a half since then, I've had light cramping, some bloat, some spotting, acne 😩 (which only happens on my period) but I took a pregnancy test & it was negative. I'm in my fertile week again this week. 
Could it just be hormones? Or is it too soon to tell with a test? I'm so paranoid about it because it would be just our luck to get preggo the first time we do it after I'm off bc & I wanted to give my body a few cycles to regulate before actively trying. 
Thoughts? ✨
