Confused. Opinions??

Okay ladies. Here’s my situation. I started spotting. And my period wasn’t due. So I was confused since I don’t usually spit prior to my period. I ended up taking two tests yesterday. Two different brands. Both had faint lines. Very faint but you could see. The second test was faint but showed up instantly. I took another test this morning and I instantly got another faint line. I went to by a digital test, and it came back not pregnant. Am I pregnant? Or could the three tests before just be wrong? I’m confused. I’ll continue testing. But has anyone had this happen before and still be pregnant?
