Announcement

So my bio mom outted my pregnancy on FB after I told her to keep it a secret, and my mom in law has been telling all her family and friends. My bf and I are done telling his family, I haven't told all of mine yet though. I wish we could post pictures on here for I could get some real advice but I'll try to describe what my plan is. I haven't announced anything on social media, but I think I'm ready to. I'm 15.5 weeks. I took a photo in a sweater that says "MOM" that my bfs sister got me for Xmas, I'm holding our cats, the picture has my ultrasound of the baby and the screenshot of the pregnancy app saying how far along I am. I'll write a caption for if I post it, but is that a weird announcement or is it fine? I'm a bit of a strange person but I feel like it's weirder to just post a sentence about it. I feel so awkward so I made the picture lol
