Faint BFPs?

Hi all! This is a tad long I'm sorry I'm just panicking 😢

My fiance and I decided to start ttc a month and a half ago. I always figured it would take me awhile to get pregnant and already gave up, to the point I had blood drawn for tests this month due to pain.

2 days ago (5 days before period) I was feeling really horrible and figured I picked up that nasty flu my students had. I wanted to rule out pregnancy because I knew that wasn't it since I had horrible cramping around ovulation and my OB figured a cyst burst. Shockingly the test was faint but positive. I took 2 more throughout the day and both were positive. I've taken tests the 2 mornings since and they are still positive.

However, they aren't getting much darker. Maybe a little but not by much. I regret testing early as I'm scared it won't stay, but I fully expected it to be negative.

Sorry so long, but did anyone else not have test lines get darker quickly? I keep thinking I peed too long or not enough or was dehydrated and it's causing false positives (I've had 6 positives and 1 negative where I chugged water and took the test right after)
