What should I do.?? 😱😳😩

So back story I have a 15 month old daughter and I met her dad at my last job then boom 💥 baby 9 months later.... fast forward 14 months I quit that job started a new job met a guy at work and now currently 4 weeks pregnant with his baby so I didn’t know he had a girlfriend before I slept with him unprotected so I still haven’t told him that I’m pregnant mind you we work together as well so he’s bound to see a bump in a few months idk if I should tell him Monday or wait until there’s an obvious bump or wait until I miss my period I’ve been extremely bloated the past few weeks so it already looks like I’m 3/4 months pregnant but he hasn’t caught on obviously but I’m stuck on what I should do I’m definitely keeping my baby but in regards to when to tell him... I just tell everyone at work I’m tired and blame my 15 month old so there’s no suspicions...

Me currently at 4 weeks pure bloatedness I can only imagine 3 and 4 months... featuring my 15 month old sleeping.!

What should I do

I keep thinking and listening to Confessions part 2 cause this situation is exactly what’s going on here.! 😩😩😩
