Please help! Am I pregnant?! Warning graphic

So my fiancé and I had sex this last time he came home (he's in the military) and he came inside me like normal.. I have the nexplon implant and I've been on my period ever sense I got it 6 months ago. Then it suddenly stopped the day after he came in me. (5days ago) And now I'm Having a lot of thick clear discharge and slight cramps and this morning I had a reddish orangish discharge. I almost thought I started my period again but it went strait back to that clear discharge. My boobs are a little sore and my hips and legs hurt a little. And yesterday I had to run to the bathroom because I thought I was gonna puke in the middle of dinner. How long do I need to wait to take a test. Please help!!
