Pregnancy symptoms?

So lately I have been super tired and always wanting to sleep. Sunday night I cried when my

Boyfriend left for training and I wasn’t even sad, I have been eating a lot of cheeseburgers lately and yesterday I ate way more than I normally ever have. My nipples are sore and I’m 7 days from my period starting. I feel like I’m always hungry because my belly is always grumbling or just I can tell I need food. Also Sunday night I threw up and then I ate a bunch of food right after And was fine. I’ve also been feeling sharp pains in my leg and if I stand up to long my feet feel like they have so much weight on them and I need to sit. I’ve also been kinda gassy. Me and my boyfriend have been trying for about a month now and had sex a few times on my supposed ovulation date and it’s only been 7 days since my ovulation date. And today I have had super watery white discharge enough to soak through my underwear onto my pants.
