Tammy • Married my best freind ❤️ We have baby #1

Aunt flow is due for me in 4 days I have taken five pregnancy test’s but they weren’t with my first morning urine and they’re all negative do you think I could still be pregnant and that the tests just aren’t picking it up or what should I do I feel like I’m pregnant but the tests keep discouraging me and I’m wondering if the negative I’m getting is really a negative or if it’s just not picking it up I have any of you ladies ever experienced this
