BFN??

Gillian • Mom of twins- 👧🏼👼🏼 10-27-17 Expecting our rainbow boy 11-1-19 👶🏼
This is my and my husband's first month of "trying". I know the chances of being pregnant are super slim, but I am 5 days late and that has NEVER happened before. I'm supposed to get a tattoo, but if I am pregnant obviously I will cancel. This looks a like a BFN to me.. But I've seen a few people post what looks like a BFN and others see a BFP!? Help!!
