Second pregnancy

Took a test this afternoon because my period is 1 day late and I have been having very light brown spotting on and off for the last 3 days. Thought I would take a test thinking it would be negative and having confirmation would put my mind at ease and my period would turn up…. did not expect such a blatant positive 😭 my son is 18 months old I’m so nervous about having a baby and a toddler!
