Could I Be Pregnant??

I've been trying to conceive with my husband for nearly 7 months now. I stopped taking birth control about 8 months ago. The last period I had was the week before Christmas. I've went all January without one and that's not normal for me. My boobs have gotten bigger and darker and so sensitive and I get nauseous every now and then and I'm eating everything that is not nailed down. I took a test yesterday and it was negative is it possible I may be pregnant and it's to early to tell or maybe my period to late?? Any help or advice would be greatly appreciated!!😊
