Im i pregnant?

So I had posted here before but sadly no one saw it, so I know I might be paranoid but here me out. I stopped taking my pill almost a month ago. Last time I had sex was on dec 27. My withdrawal bleeding came the 12-14, I took last week a pregnancy test it back negative, I took a blood test and it was negative. However, I’ve been feeling dizzy out of nowhere, and I’ve been bloated as well. Is there any chance I can be pregnant? Please help I have to test on Monday to ship to basic training and i don’t want them to find Im pregnant there, it’d be so embarrassing.
