17 and tons of pregnancy symptoms?

Hello, I know this is a little odd considering my age, so please don't judge as if I am it was entirely accidental. I had sex with my boyfriend everyday in the week of the 17-23 of April and in two of those the times the condom broke. (Once was understandable but twice..?) They broke on the 21st and 23rd and my period wasn't set to come until May 7th but it showed up on April 29th. It wasn't a regular period though, it was super light pink and then a it was like brown spotting and lasted only for two days. In the day I was spotting brown I got a really sharp twinge of pain in my uterus and since then have been having very mild cramps on and off. I've been eating like a pig which is highly unusual for me being as I usually only eat once a day. Almost every day I've been experiencing discomforting pain in my lower back, though it's nothing to bad to make me take pain medicine. I was constipated for a few days but yesterday and today I have really bad diarrhea (TMI I'm sorry) and the cramps aren't regular cramps now it feels like tugging or stretching. Also I have this really creamy white discharge coming out quite often, more often then it does between my regular periods though it's still virtually odorless. Also I usually only go pee one to two times per day and for the last week or so I've been going pee four to six times per day. And again TMI but my pee has tremendously changed in color it's like yellow now and oh my god the smell is awful, so much so I feel the need to spray air freshener after peeing. I've also been extremely tired the last few days. I slept for twelve hours the other night and still was tired all day. Twice since this "period" when I stand up after laying down I have to sit because I got extremely dizzy. My breasts were slightly sensitive the first day or two but are fine now, though the areolas look slightly darker? And I don't feel nauseas but I have even getting an overwhelming urge to vomit, though it never comes. Any thoughts? Please no negativity.
