How did you drop the news?

B🌹
I just found out last night that I'm pregnant with my 2nd! Af is a few days late (either 13 or 18 dpo when I got my BFP). But I don't know how to tell my husband! I took a 2 week trip home with my son to see family and found out 4 days in. I'm thinking of waiting it out until I get home in a week and a half just to make sure it's not chemical. <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> says I'm 4wk 5d and ovia preg says I'm 5wk 1d so I don't know what the chances of it being chemical are. What should I do?! Thoughts?

It was so funny last night because I took the test and acted like I just went to pee. My mom then says "oh, I wish you were pregnant right now!" What are the odds of that? Lol...
I'm going to wait until 2nd trimester to do a family reveal. I wasn't able to do any of this stuff with my first. I'm just hoping for a sticky bean!
