Feeling fed up

I was a week late on my period & it usually is 5 days, this time around it was 4. Horrible cramps. I haven't had any PMS signs since I was a teenager & I'm in my early 30's. My breasts have been painfully sore for 3 wks. leading up to my period. I finished this past weekend & they still hurt. I've been nauseous for 2 days now & constant migraines. I've noticed I've been breaking out on my chin lately too. My stomach feels bloated. I doubt I can be pregnant, since I had 4 days of a moderate to heavy period. It's hard to tell when I ovulate even when using apps, because month to month I'm usually off a day or 2. This nausea is something else, not to mention I almost passed out at work this morning. I've been taking Prenatal vitamins for about 3 mths. now. My boyfriend & I have been trying for almost a year & nothing. I'm confused on if these can be early pregnancy symptoms or am I fooling myself? I have my yearly in 2 wks. Trying for so long & nothing happening every month is emotionally draining. Any feedback would be appreciated.
