Joint pain and flu symptoms in early pregnancy

So I’ve been off of birth control for about a month and half, and we have been tryin for a baby. These past fees days I’ve been having stomach issues such as throwing up and diarrhea (sorry tmi), but I feel like that could’ve been food poisoning from the night out we had. But this has still been going on for a few days, just not as severe. I also have been experiencing joint pains, muscle aches, and a bit of fatigue. I would normally think that maybe I just have a cold, but I feel nothing like how i usually do when I have a cold. It just feels like I worked out super hard and I’m sore. Could this be a pregnancy sign? Thought it was kind of silly, but literally have never felt this kind of achy pain before
