maternity bras vs upsize regular bra

Brooke
I am already big breasted at 38 DD and currently my bras are mashing me and I'm sore. I'm 7 weeks pregnant. What maternity bras do you recommend this early or should I just stick to regular and upsize? Also, I am really trying to lock and load these suckers because they hurt and feel they weigh 100 lbs each when bra comes off.
