Finding out that you're pregnant when late

Lucy • I`m 23 and my husband is 29. We`re pregnant with baby number 2 due september 25th!. We have one perfect boy 💙 baby dust to everyone :)
Hi, has anyone been pregnant before and found out straight away then with their second pregnancy not got a BFP until about 2 weeks late or later? with my son I found out I was pregnant when I was 1 week late but I am now 2 weeks late with no signs of AF. Thanks!
