Positive then negative...

I decided to buy first response pregnancy tests today instead of my normal dollar tree tests because I just have this feeling I’m pregnant... when I got home tonight I couldn’t wait and just decided to pee on the stick. And guess what?? It was positive within a minute! I was so excited I took off running and screaming through the house to find my husband. When I got to him I said “look we did it!” And handed him the stick. He looked at it then at me dumbfounded and handed it back. I looked at it and it was clearly negative. I just started crying... he said he could still see something forming but there was clearly nothing... I’ve never felt more defeated... it’s been 6 months. I know that’s not long but tonight it feels like a lifetime...
