Hopefully pregnant!

So this is probably me being paranoid because I want a baby lol but I got my first depo shot in November, but I didn’t go back to get it after the 13 week period, and I got it again June 1st because I wanted to get on the pill to regulate my period but they thought it’d be best to get the shot until I can get in somewhere else. Well long story short, I was bleeding a lot all the time and 2 days before the shot it completely stopped. Well in the last 6 months my so and I have been having completely unprotected sex and now that I’m no longer bleeding I thought it could be the shot, but I’m incredibly nauseous like more so then the first time I’m napping any and every chance I can. My boobs are incredibly sore and my nipples look bigger and a little bit darker. I feel super bloated. I’ve been having mood swings like no other. Like super super angered super fast. I took a test yesterday (it was a cheaply from the dollar store) and it came out negative but it was also in the middle of the day. I have milky white discharge! What do y’all think?
