Preggo symptoms but ovulation dates don't add up?? Pls help

I'm new here so excuse me if I'm not posting in the designated "possibly pregnant" community, but my period is not due until the 26th, I'm impatient and would really appreciate some other perspectives! To start, my breasts have been sore (mainly at the center/nipples..and they're sore enough for them to hurt when I walk down the stairs), I'm peeing a bit more frequently than usual (though it feels kind of like a UTI?), I get minor headaches on and off throughout the day, and on Monday morning, I got very hot then nauseous and ended up regurgitating. I'm not one who typically throws up, even when I'm sick. I have a fairly strong stomach when it comes to throwing up so it took me by surprise a bit. Since then, I've expierienced aboit 2 subtle waves of nausea (one being from my mother's crazy driving). I've also had random minor cramps (I'm not sure if thats what they'd be called..some are more intense than others and some last only 3 seconds or some last 3 minutes) in my uterus. They're not nearly as painful as period cramps. The more intense/fast passing ones may make me sort of go "ouch!" out loud for second but thats really the extent of it. And the most painful uterus attacks are always only for a few seconds. Now even though I have these symptoms, what throws me off is that I haven't had (I still don't have) really any vaginal discharge. I'm sort of dry down there. The only discharge I have is when I'm about have sex with my SO. About a week ago, I had sticky white discharge on my panties for a day and that's all I've really had (aside from the fluids that come when my SO and I are about to...you know) since the 1st. My estimated ovulation dates were on the 12-14th but I still had no discharge really and my peeiod endes on July 31st. So the dates seem a little off which is why I'm so confused. Does this sound like what I think/hope it is? Any replies are helpful! ♡
