Hey ladies!

So my period has ALWAYS been irregular up until 4 months ago (I’m 21) the past 4 months it has been regular and with in a day or two of when it is supposed to happen. My and my man do not have protected sex and we are officially trying starting this summer once our house is completed. My period was a day late so we took two blue dye Walmart tests and they both came back negative. Two days ago my nipples started hurting, and smells started making me puke. Like fresh baked goods and dog kibble. Now my period is 5 days late, I feel bloated and off. I don’t know if I should just leave it or test again? Thoughts?
