Could I be pregnant?

Frances

Ok, so here’s the deal... im 18 days late, sore breasts, nausea during the day, a bit of indigestion when I eat, BUT I took a HPT when I was 7 days late and it was negative... I havent wanted to test again dreading that single line... Im 34 obese and have PCOS... could I be preggers or could this be just a skipped cycle? Trying to reeelaaaxxx
