Bloating, sore stomach boobs swelling

I've been read up a fair bit since me and my partner have finally decided to go ahead and try for a child. But last week 3 days before ovulation kicked in we had unprotected sex, now I know it has already been a week but I myself can see dramatic change in my body since i'm a very small framed skinny girl.

Recently my stomach has bloated and it is very recognizable I honestly look 4 months with an full bladder, it's also becoming hard and small cramps that i have noticed have not gone away after I use the bathroom or eat until i'm satisfied.

I've been feeling a bit gassy and wow they are something a lady should be ashamed of, I have been peeing a lot and my very tiny almost flat boobs have all of a sudden started to fill out and felt very tender not so sore but a lot more sensitive then normal.

I've also noticed slight weight gain, again this is all very noticeable because i'm an naturally very skinny flat stomached and almost flat chested female so all of a sudden my shirts are stretching from my bloatedness and my bras are overflowing with boobs.
Lastly Tiredness and feeling very hungry, like I would eat my standard meal and it wouldn't feel like it impacted on my belly.

Now I'm still about 2 weeks away from being able to test for a pregnancy but i'm wondering of these are good signs since I have a pressing matter that needs an answer next week...and if I can shrug these off as not pregnant I can make this matter a lot easier for my partner and he can be here when it all starts to happen.

So you can see my predicament here since I was not expecting all of this to happen so soon, before you tell me to wait and take it a few days after a missed period and i'm not holding my hopes up but all I'm really asking is If these are good indicators of a body getting ready to carry a baby. It will take some stress away and answer a few questions.
