Don’t wanna get my hopes up

Okay to begin, me n my bf have been having sex almost every other day my whole cycle up till now which is cycle day 28. (About 11-13 dpo).

My cycles are usually about 30 days long. I know the only way to really find out is to test but i don’t want to waste money if it’s just me being in my head. The only things that are pointing me towards that I might be pregnant is that I’ve had very very sore nipples and tender breast for a little over a week now which is very uncommon for me, usually when I pms I just have some discomfort and twinges of pain here and there but nothing like this, and I’ve been getting dizzy a lot and nauseous a lot. Also been quite tired, but I also know that these are pms symptoms as well. So basically what I’m asking is that in your opinion, is there a high chance that I could be and should go get a test today? Or am I just stuck in my head with baby fever and should just wait a few more days? Thank you 🙏
