Thank you everyone for all of your help
Do you have craigslist where you live? They usually have some good deals on there, sometimes stuff for free. I would also say to ask friends, because it is not unusual for a women to have a bag of stuff sitting in the garage waiting for a future pregnancy or someone who wants some maternity stuff, I know I have my stuff sitting for 2 years and if anyone had wanted to use it I would have let them borrow it! I would also say checking good will and salvation army. Plus check your husbands closet, my husbands PJ pants work great for me when I am lounging around the house.
Check out the local Good Will or Salvation Army, you might be surprised at what people bring in there! They often have a maternity section :)
Btw freecycle has free stuff only!
I got my clothes from Hope, similar to Goodwill. Tops are easy to find, bottoms are harder in these stores. Also try freecycle.org which is like an online flea market. Good luck.
