It's only been a few weeks since we learned that Erika Christensen is pregnant with her first child. Seeing as the actress held onto the news until she was seven months in, though, it should come as no surprise that she's showing quite a bit.

That's not the only picture we've seen since the announcement, either. Keep reading for all of Erika's bump snaps so far, then check out the gorgeous pictures from her 2015 wedding to Cole Maness.
