Such a positive test already

Ch

My period isn’t even due until Wednesday or Thursday and my tests are getting a lot darker. I don’t think I ovulated early since I chart and use ovulation tests. My egg white cm, temp, and positive opk was all in line in the same same day. Also I’m already getting kinda sore breasts and nausea. Anyone else get symptoms or such a string positive this early? I’m taking all this as a good sign since we had a loss last year. I keep telling myself this pregnancy will last this time.
