Do I mention to my friend or wait for her ?

My friend is recently pregnant and had her first 12 week pregnancy scan this past week- but I haven’t heard from her about it yet…. Do I reach out and let her know I hope she’s doing ok? Or do I let it be and wait for her to reach out… I don’t want to force a convo if there’s sad news from the scan- but I also don’t want her to think I don’t care?
