Hello. So here's the situation I am currently facing. I am currently 9 days late with numerous Negative results. In theory I would be 5 weeks pregnant. As I read what might be the corporate I find stories in which woman attest to not getting a possible with a home test until after 7 weeks pregnant. Has anyone had this before? Any info/stories? I feel so confused and well it's making me anxious and nervous... I also read that low HCG means possible miscarriage.
