Possibility of pregnancy?

Zoe
Hi I'm 7dpo been feeling sick since about 3dpo, sore breasts at night for the past 3 nights, soooo tired all the time and dull hot lower back pain for the past few days, I have had 2 pregnancys in the past year one mc and one was ectopic and had my left fall tube removed, experiencing the same symptoms as when I had the ectopic, in August so scared has anyone had these symptoms and had a successful pregnancy? Not that I'm pregnant although I feel it...xx
