Odd pain

So I couple of days ago ( must of being around 5dpo lasting till 8dpo) I had a really bad bruised feel in my tummy it felt like I had done hours of sit ups ( i don’t exercise 😂) that lasted for a few days it was also my left side that had this pain. My friend said to do a test as that what normally happens when you are pregnant. Can anyone back this up? It wasn’t painfull just uncomfortable! Yesterday I had really light blood in my underwear and when I wiped?

But the weird thing is we had unprotected sex around ovulation and then again 5 days ago. the only time he came inside me was 5 days ago? Could I be pregnant I’m really confused?! I never have any bleeding leading up to my period and I havnt had any since yesterday?

Last night I had a dream and got a positive test but then again in the dream I did another test and it was covered in blood? ( I know they are only dreams and can’t really go by them) I’m just so confused :(

Help?!
