I need your opinions, ladies!

Melissa⚓?

Okay, so my period was do on the 14th and I didn't start until the 20th. I know it's common for an irregular period. I was a little nervous at first but once I started I didn't think anything else. My period was very unusual. To a point when I completely stopped on the third day and started again that night. I still didn't think anything of it. I got off my period on the 24th. This past weekend my hormones have been out of wack and I've been very irritable, still I didn't assume anything. Sunday, on the 28th, I had a spot of blood on my undies (sorry for the tmi..). That's when my interest peaked. I took a pregnancy test Monday morning & I'm not sure I waited as long as I should have. But there was no pregnancy line. That night, I went to hide it in the trash can and decided to make sure. There was a faint extra line. So, I took a test Tuesday morning, & I know I waited long enough, but there was so line. So, my question is, do you ladies think it was just a false test and I'm not pregnant? Or take another test soon?

Sorry if I didn't make a whole lot of sense.

Thank you!
