Line progression stress!

Katie

I started out with super super faint lines at 9-10 dpo and just can't get myself to stop testing! I felt like I was getting good color change at first but it feels like it's slowed down. I keep telling myself I'll stop when the test is just as dark as the control but I'm now 4w3d and that hasn't happened yet. I also had some pretty strong cramping on my right side last night (same side where I would always feel ovulation pain) but I can't help worrying and thinking it's an ectopic pregnancy, even when the pain will go away from hours at a time and when I've been up and moving more. This is also my first pregnancy so I have no clue how my body will respond to being pregnant- so far it's been mega bloating with mild waves of nausea and the cramping. Advice please!
