confused?

So my period has always been very irregular and being on depo only made it worse. Well between September and December my period was basically regular besides October when it skipped that month. Well come January I had this weird spotting for a week and my periods are usually at most four days. Well since January I haven't had a period at all. I've had random cramping on my left side mostly. I'm very sensitive to smell and have been for a few weeks and also every single time I eat it never fails I feel like I'm going to puke. I've also been quite irritable lately. I know I need to take a test I'm just hesistant because I'm so sick of seeing negatives. My boyfriend and I went out tonight and we're talking about being pregnant and he goes I can't wait to have a baby! ❤️ I used to be so constant on tracking and taking tests and I just got fed up so since about January I've stopped caring and I honestly think it's a possibility I could finally be pregnant I'm just to nervous to take a test. Thoughts?
