Confused after Ella Emergency Contraception!

Tiffany • Im 23, married to a wonderful man, have a beautiful 4 year old daughter, and currently in Mexico. 🇲🇽🇲🇽🇲🇽
I don't know where else to post but I'm almost 100% positive I'm not pregnant. I have taken Plan B in the past like Next Choice and Glanique. But I bled a normal period every time. 
Short story. 
Me and my husband had a moment (he didn't pull out) and he said because he's ready for a second child. However; the next morning, he surprised me with a Plan B pill called Ella. I took it. Everything was fine. I found it strange however when my I still had symptoms almost two weeks after plan b. I got confused. Waited for my period. Sunday- very light pink spotting. Monday- very light pink-brown spotting. Tuesday- red blood (only 2 pads, weren't full) Wednesday- brown spotting, very little. Thursday- brown spotting, very little. Friday- brown spotting, very light. Saturday- brown spotting. Sunday- nothing. 
I found this on the drugs website and am now wondering "am I supposed to get my normal period?" "Did I miss my period if i only spotted for 6 days?"
And main questions "should I suck it up and take a pregnancy test?!" 
Should I see a doctor? 
I know the pill can mess things up especially your cycle but I dont know if this last cycle is considered a period.. Im just so confused.
Any help is welcomed. Thanks in advance. 
(I seriously don't know why I haven't gotten an answer from 1 person.. So frustrating)
