Pretty upset

Samantha • I have an amazing husband we have been together 7 years we have a beautiful little girl who will be 5 in April! We have been ttc since November 2014. I'm a dog groomer 😇😉😍👪💖
So I found out I was pregnant two days ago I've gotten nothing but positive pregnancy tests since then well today I went for my confirmation appt and they told me my pregnancy test was negative I said that's strange because I have all these tests saying positive I asked to see the test and she brought it to me, well guess what it was positive. She was like well its barely there come back next week to retest I told her that's fine that I'll come back but that's a pretty clear positive and I don't know how she didn't see it before. Well they sent me on my way and I go back next friday! Idk I'm pretty mad right now
