I am 22 weeks and I am still in my regular clothes but probably within the next few weeks I will have to switch over. I wear some of my maternity pants but no shirts yet. I have not gained any weight, actually lost 4 pounds.
I swear I was bloated like 3 weeks after conception. I went to Old Navy and bought some maternity jeans to buy some time before I bought additional items. I suggest Noppies pants. You can wear them from the beginning until after you give birth. They have great stretch and are very flattering! They cost $98, but if you were to buy pants for each trimester and for afterwards you would surpass that price.
Re: How far along were you...
Depends..I had so much bloat that I statred to wear loose clothing at abut 8 weeks
