HELP PLEASE

Need some help,

I last had sex on the 8th April. I then had what I thought was my period on the 23rd April, bleeding was a lot lighter then normal and from what I can remember I wasn’t filling a tampon, which I usually do quite quick and my period was over within about 2 days.. which again isn’t normal for me. Since then I have felt rather nauseous, I have had dizzy spells throughout yesterday and my stomach feels so bloated and uncomfortable.

I’m taking a pregnancy test in the morning, buying one this evening - my question is reslly has anyone experienced this and being pregnant?
