i presumed there was a "right" time to do it. Then i became pregnant, and found myself with sore breasts at 8 weeks pregnant. So i went to buy one, feeling embarrassed i needed one so early, purely to stop feeling so sore. The relief was immediate, as soon as i had a maternity bra, my breasts were properly supported, and i stopped feeling sore.

i assumed everyone got bigger breasts as their pregnancy progressed - i was assuming i would have to buy maybe three different sizes throughout the pregnancy. To my surprise, i bought a 12DD at 8 weeks pregnant, and each time i checked with a fitter, at six months preg i still needed a 12DD, and once my milk came in (after baby arrived), although i FELT like Dolly Parton, i still needed my 12DD. It wasn't until about 8 months after my baby arrived, that my bra size changed. So i got a really good wear out of the first lot of mat. bras. After 16 months of wear, i needed new ones anyhoo. Maternity bras on me, got a much bigger workout, than normal bras - constant wearing them, and i had less to rotate, compared to normal bras pre=pregnancy.

I struggled trying to work out my size, in the shops where you fit yourself. I ended up going to a shop where they had a fitter, much better result.
