Help: Am I pregnant?

I know this is so silly to post about, but I'm going to try and make this as quick and factual as possible.

So a few days into my fertile week I had sex - with a condom, no other forms of birth control - and felt a little queasy the next day. I saw him again a few days later, same circumstances, felt a bit sick again. A few days pass and my stomachs been uneasy, I'm feeling a bit nauseated, sometimes I'm indulging in foods and other times I feel like I couldn't force myself to eat. I'm constipated, I've been sleeping more, I'm bloated, my breasts are a bit tender, and I'm certain I'm peeing more.

Now, I know the mind is powerful, I'm aware that it's possible that I've been so focused on the possibility of being pregnant that my body could've actually manifested symptoms of pregnancy. I'm also aware that some of these can also be symptoms of PMS, as I am now approx 7 days away from my expected period.

So, I know we're not all doctors. And of course, I know condoms are only 97% effective (is it 99%? Regardless) - so I'm not asking you to tell me "well it's possible because..." but I'm more looking for other women who felt symptoms of pregnancy early on, were you right or wrong? Are these symptoms psychologically-manifested? What is the likelihood these symptoms are indicative of pregnancy in my circumstances?

Thanks xx
