need advice

so i announced earlier that we were pregnant but I've read up alot on the test i took and ive seen an I'm hearing alot of bad stuff about these test i took all these test and i didn't test the time frame the testline came up around 10 mins after yesterday

and they got darker the longer they sat so this morning i woke up and took this one and timed it and i didn't let it go past the 5 min mark before i took this pic

but now im obsessing i don't feel pregnant im tired but that's an always for me i am 7 days late on my period and my periods are always normal but ive been on google so much yesterday and today just to get conformation that i am and i really think ive brain washed myself into believing im not! im praying we are when my husband gets off work we are going to go buy a first response so i can stop obsessing has anyone else ever had this issue like i want to believe it but I'm scared I've had 3 miscarriages already. and the reports on these test are horrible
