HELP!

Hello everyone, so couple questions…

My boyfriend and I had sex on my ovulation day, I was late for my period, the day after I was supposed to start I was spotting very lightly and also had “brownish” blood (which could be implantation bleeding) I started bleeding how I normally would on a period but it did not last my full period length and shortly after was very lightly spotting. I’ve been super emotional, crying easily,getting upset over minuscule things (which I chalked up to PMS) started having motion sickness today (which is NOT common) I did cramp… but it wasn’t my normal cramps, breaking out in areas I normally don’t. I did buy pregnancy tests but I also don’t want to be saddened if it comes out negative. Any thoughts/opinions are appreciated and welcomed.
