Does anybody see anything?

Emily • Greenlea Anne Harrison arriving December 2018

I've been taking OPK's and last week I was very very emotional, now I've been crampy and super tired, could this just mean AF is about to show up? The last time I was pregnant (2012) my first sign and I didn't realize was sore boobs and after 4 positives on three different brands I miscarried 3 days later. No sore boobs this go round. But I just want to make sure I'm not seeing things.
