Can you help ease my mind

Hey mamas! I just found out I’m pregnant with baby #2. I’m using a donor who I do talk to and for some reason he believes this pregnancy is going to end in a chemical so can you guys help ease my mind a bit. The tests are getting darker slowly but I’m testing a lot so it could just feel slowly. (Second pic is at night 8 DPO and first one is this afternoon 10 DPO) 8 DPO is so faint you can barely see it and today at 10 DPO it’s very obviously there. Any advice? I know I’m still early and there’s a chance of a chemical but does it look like it’s going to happen?
