Pregnant?

Hello beautiful ladies🥰

So I have some concerns and I need all of the knowledge right now😩 so I missed my period it’s about a week and a few days late now and when I took a pregnancy test at home it came back negative... so I went to the clinic but when I went to the clinic it can back negative as well🤔🤷🏾‍♀️ I’ve been very nauseous, can’t finish my food without feeling sick, peeing a lot, and for a while my bowels were green. Ladies help could I be pregnant or its it just too early to tell? Also I would love to hear some stories.
