Feeling crappy

Nicole

So I have been feeling uncomfortable in my lower abdomen for DAYS now and I am 2 days late with AF. I took a First Response test that detects 6 days before your missed period Thursday night.....solid pink line. Just took another test with my morning urine....solid pink line. I still have the uncomfortable feeling in my abdomen and can feel myself stressing out now big time. I am never late maybe by a day that’s it! Advice please.....
