Possible Early pregnancy symptoms?

toni
Today I'm 7dpo. Yesterday I had sore breast, fatigue, and when I went to the bathroom and wiped there was pinkish brown discharge. So this morning when I woke up its still there and lots only when I wipe and been cramping bad today and even dizzy spells. Could the discharge be possible implantation maybe? I'm having all the symptoms and praying this is it!
