yes! we only dtd once during the month as we were both so busy. at 9dpo i was at the shops and saw a pregnancy test on sale and thought "may as well buy it", not thinking that i'd use it that cycle. but that afternoon i thought even though it was probably too early to test that i would. i wasn't a habitual tester or anything like that, it was just an impulse to test. BFP came up faint but straight away. bub #2 is due in april! dh is still in shock that it really can happen from one BD!!
