Pregnant?

My mother is 13 weeks pregnant, and she’s 43. I am 25 years old. Some people say I may be feeling like I am due to her hormones. It’s been two weeks that I have been tired, I sleep a lot. I also crave things out of nowhere. My last period was January 30-February 3, I took a pregnancy test two days ago and it came out negative. Today I bled a little, and I also found out Chinese food grossed me out and almost threw up. I have lower back pain. But other than that I don’t have other symptoms, could this possibly be a pregnancy? Even if the hpt came out negative? I have history of ectopic pregnancies and had a left salpingectomy.
