Please help 😢

I have a coworker who recently had a stillborn. I don't know the coworker well but she is extremely sweet and kind. We would occasionally check on each other because we were both pregnant (within a few weeks of each other).

She just returned to work (some 5-6 weeks later). I just want to hug her and show her so much love...I was going to buy her some flowers and a card today...

But is that appropriate in this situation? Especially since it's been a few weeks?

I'm also afraid because I now have a large baby bump and I don't want to make her feel sad or uncomfortable. But I also don't want to avoid her because I want her to know that I am there for her.

What do I do?
