Negative test mix up

For the past year and a half my husband and I have been trying so hard to have a baby. We have had two miscarriages in this time, but have not given up hope. My husband is in the Marines and is out in the desert for a pre deployment training. Before he left we were still trying (Left 3 week ago). Well my period is now a week late so tonight I took a test and I had a friend with me, I handed the test to her to see first and she yelled “you’re pregnant” of course I was so so happy and started balling my eyes out and look at the test seeing and thinking I am. Well after a while of happy tears I decided to google the test, the test was different than I’ve ever taken and turns out it was negative. With my husband being away and having that false hope after trying for so long I can’t help but to be heart broken. I could use any prayers or just positive thoughts and advice right now! Thank you all for listening
