Worried

ok so I'm very irregular, I was one week late but had some spotting and that was it so I didn't think much about it but now I'm having nausea and very sensitive with scents and I'm a bit bloated. I was anxious and took a pregnancy test it looked negative but the control line was half way and I drank a bunch of water and coffee prior. Now I have to wait for the morning. I hope I'm not, me and my boyfriend just recently had a bad breakup :(
