Have I lost my baby? Please help anybody

Ok so I had a positive lloyds test 3 days ago... Doctor confirmed I was pregnant and referred me to midwife for May 3rd... I've since had 5 negative tests... 2 normal clear blue, 1 lloyds, 1 cheap asda one and 1 clear blue digital. I am so scared incase I've lost my baby. Has this happened to anyone else?
