help!!!

So this weekend my husband and I went out with some friends, had a few drinks and I got extremely sick! Nauseous, vommiting, the whole nine yards. I have been really crampy lately like the past two weeks, and really bad indigestion. I had my nexplanon removed a month ago and we have had unprotected sex numerous times. We weren't really planning on trying so soon, but then again we aren't preventing either. I took a home test and it was negative but some girls at work were saying that I could still be in the very early stages and so it wouldn't show up, and maybe that's why I got so sick from a couple of drinks. I would never drink if I was pregnant but now I'm worried that maybe I am. Do those symptoms sound typical for others??
