Implantation or pregnancy

My cycle is typically 27 day’s occasionally has been 28 or 26 but flows ovulation prediction is always inline with the clear blue sticks I take.

This month I was expected to get my period today, Thursday 9/14. On Tuesday evening (11dpo) I was having a lot of discharge at night that turned into egg white discharge which had a small hint of pink to it. That night I threw up after eating dinner and felt extremely nauseated.

Wednesday afternoon (12dpo) when I wiped there was dark brown blood (not heavy), for the remainder of the day any time I wiped I had dark brown or light pink blood. That night there was some red blood that came out without wiping on a pad but not enough to fill a pad. I felt sick after eating dinner but did not throw up.

Today, there has been some light spotting but it’s back to being brown and seems to be getting lighter as the day has progressed.

Other symptoms I’ve had was lightening pain through my boobs, soreness not on my nipple but underneath, bubble sensation in my stomach along with pin prick pans stretchy pains, lower back pain and extreme thirst.

Do we think that is my period coming two days early or could this be implantation bleeding?
