Advice ... please :)

I am currently 4 weeks and 1 day pregnant have been having symptoms already. Feeling a bit sick, boobs really sore but feel like I have horrible tummy cramps like period pains, and they don’t seem to be going, (for like 2 days) I feel massively bloated, and I don’t know whether I should be worried about the cramps it just feels like pressure all the time sometimes there is a sharp pain but it’s happened a few times on both sides.. I have not had any bleeding just a little tiny bit of discharge. I’m just getting a bit worried as today was the day my period is due. I also had a miscarriage a few years ago which was VERY early so I’m getting a bit worried now. What do you think?? I’ve had positive pregnancy tests for 3 days in a row now.
