Early pregnancy symptoms?

[boxer_mama]

My last period ended May 2nd. My boyfriend and I have had intercourse 3 times since then, using a condom every time. None of them broke. I am adamant about using protection but a week and a half ago, he did enter me without a condom for less than 15 seconds. He did not thrust or have any pre-ejaculate on himself prior to this. That's not to say he didn't have any inside of me, but he wiped himself off beforehand. My next period isn't due for about 2 weeks. I know I'm probably psyching myself up and I'm fairly certain it'd be too early to be having symptoms but I decided to ask anyway.

I've been having more frequent bathroom trips to pee but this was happening before my last period. I have been cutting soda out of my diet and drinking more water instead which could explain it. I've also felt exhausted recently but that could be because I adopted two dogs last week and have been up early to walk them and feed them. One has a health condition which requires maintenance throughout the day. I've wondered if maybe my nipples are darker but again, that could be my mind playing tricks on me. I've been having thick, odorless white discharge lately which I've read can be an early pregnancy symptom. It's been occurring for about a week. Today it's a lot thinner but still somewhat pasty. I have felt a lot gassier and more bloated lately. My diet has been somewhat iffy which could explain it but it still feels odd.

Any input would be appreciated!
