Missed period chronicles

Today is day 2 of my missed period, no sign that AF is coming this month.. Hoping this is it! A little nervous if I get a BFP because my fiancé changed his mind about having a kid right now and we haven't been on good terms lately 😕 I know it would be selfish to abort (something I would never consider) but how could I get him to be excited about having a baby? He used to be ecstatic about the thought of procreating but now it seems like he's lost interest and wants to wait... What should I do? I've tried talking to him about it and he keeps bringing up abortion but I'll be a single mother before I do that. Any thoughts? Try to keep them positive please!
