Looking for advice...

Ca

I play soccer in a coed league and now that I am pregnant I am going to stop playing (I’m the goalie, so there is a lot of contact, obviously not safe for pregnancy). I am not planning on telling people I am pregnant until I’m out of my first trimester, so I’m trying to figure out what to tell my team about why I am suddenly not playing for the rest of the season without just telling them I’m pregnant. I am friends with all of my teammates so I will continue to see them socially, so I can’t just make up an injury or something. Thanks for any ideas you guys have!!
