caffeine when pregnant first trimester
Now, keep in mind, thatâs a lot of coffee, probably more than most people consume, and certainly not advised for a pregnant mama. (There was also a 2001 study that showed that consuming more than 300 mg of coffee while pregnant doubled a womanâs risk for miscarriage in first trimester (2).) Up until 2008, the general consensus was a few cups of coffee was fine during pregnancy.
