Hi, I m a female who is sexually active. My partner uses condoms. We always use them except one time about 1.5 months ago. My period is 7 days late, I ve been nauseous, dizzy, bloated, tired, and had constipation of late. I ve taken 2 Home pregnancy tests which are both negative. Should I wait a few days and test again or go get a blood test? I have been under down stress as of late, so wasn t sure if this would cause a delay like this.
