Bfp still very light after two days! Is something wrong?

I got a very faint bfp two days ago at 10 dpo.... so I waited until today....12 dpo to take another test just to make sure and to see that line getting darker. It didn't get any darker at all! It still took a couple minutes to show up.... But both were def in the time limit. I am so worried I'm going to lose it! They are both too light to show up in pics.... But are def there. I think I had a chemical last month although I never got a bfp. Dh had pretty much changed his mind about having a fourth so if I lose this one I prob won't get another chance! Af isn't due for two more days. Oh.... And they were both fmu but today I peed in a cup and dipped it. IDK if that makes a difference. So what do you think? Am I just driving myself nuts or should I be worried about losing it?

Try not to worry, I drove myself nuts with "line progression" but really mine wouldn't get darker but every 3 days.

This is true....it can take a day or two for hcg to get higher......try not to worry

Thanks girls....I know in my head it doesn't really matter but the heart is a very different thing! I took another one this afternoon And its a little darker. So hopefully everything is okay! Seems like forever till I'll be at the doctor and getting confirmation. Once I see that little heart beat I'll be fine!

I'm telling you I saw that line
