Possible IB or AF.. What do you think?!

So, the last week of so I've been very fatigued, tired, moody, my breasts had a burning feeling a few days ago, my lower abdomen has felt full and I've had some mild cramping on and off. This morning when I woke up I felt nauseous for a bit and my nipples were itchy. A few hours later I went to the restroom and when I wiped there was a lot of whitish/clear almost egg white kinda discharge with a little bit of pinkish blood in it. It's been 7 hours now and I've had no more spotting at all and cramps are gone.. I'm 10dpo today, do you think it is possible implatation or it's the begining of my period? I guess only time can tell, but I'm anxious!
