Can somebody ease my mind😭

So I got my BFP 1 week ago on that pink amazon cheapie at the top. I ran out of those and bought the white strips (because they were literally the cheapest i could find with more in a package) and I’m just concerned because the line intensity has not changed at all. But I think my first responses look okay.. however I ran out of the FRER and I officially missed my period today so I took a FRRR (rapid result) today and I feel like the line is a bit lighter than what it should be. But I’ve heard the rapid result needs to pickup more HCG than the early result so that might be why. My fiancé’s birthday is on Saturday and I’m really looking forward to surprising him and having a healthy pregnancy. I’ve had a chemical before so I just can’t help but be worried. I think I’m going to stop testing. Looking for opinions and advice. Thanks for reading❤️
