Should i retest?

My period just ended Wednesday (march) but wasn't my normal period. It came late and It wasn't heavy just light and this time lasted 6 days in February was 4 days which my usually my flow goes from heavy to light and horrible cramps. Last month was light and spotting and no cramps like this month. It's unusual for me. Well last month i started feeling nauseous and started throwing up and it's been happening this month too. I been having low back pain and headaches. My appetite had increased the last couple weeks but now it has decreased and even water makes me nauseous. I noticed i wake up and im just so bloated my jeans fit too tight. I been moody and emotional my breasts keep itching and feel tiny bit sore. My last two periods been weird and this started happening last month. Which i did have sex January and February. But im thinking since my period is over i shouldn't be feeling like this no more.

I did took a test early last month but it. Looked negative to me but two women on here they saw something. I have a digital test left but i don't really want to use it maybe cause i don't want to be disappointed and i did bleed last month and February. So I'm confused.
