Curious and nervous

Me and my husband have been trying to conceive for the past year. On 3/1 i was exceptionally nauseous and decided to test and got this faint blue line. I chalked it up to evap and decided to retest a few days later because it continued to consume my thoughts. I received another faint blue line, but wasn’t entirely certain due to miscarrying before. I tested again today and again a blue line. All within the 10 minute window and all blue. The bottom picture is today (don’t mind the silverware). Is it possible to be an evap or false positive? I don’t want to get my hopes up when it’s been countless negatives and tears shed over this.
