Brown spotting, BFN.

Amie🕊 • My husband Tom and I have been married for 2 years. We are down to the final 30 days with baby #1! Fingers crossed that this all goes well!
Had some light brown spotting once on the 19th and once on the 20th. AF is due between this Thursday the 26th and Friday the 27th. Took an at home test yesterday (Monday the 23rd) first thing in the morning and got a BFN. Not sure what that brown spotting was about. Too soon to be my period and have had nothing since. Assuming too late to be ovulation spotting. Was really hoping for that BFP. 😐
