Maternity clothes early?

I'm 6w5d with my first set of twins. This is my 4th pregnancy. My last pregnancy ended in a miscarriage. I have two daughters 10 and 3. I'm not a skinny girl. I had a little bump from having my kids but I'm so bloated and my lower belly is sore and regular jeans are getting too tight. So I got out my maternity jeans and feel so much better! We are telling friends and family so I don't need to hide my belly. These are my double rainbow babies and after over a year trying to get pregnant I'm just so excited!!
