I never drank coffee before I had DD1 (the sleep deprivation nearly killed me, I soon realised the only way to get through those 3-hourly wakeup was COFFEEEEEE), but I gave up when TTCing DD2 because I was drinking lots of coffee when I had an early m/c not long after DD1 was born. In all honesty, I don't think the coffee was the deciding factor in my miscarriage, I was under a lot of stress and probably not fully recovered from giving birth so I don't think bub would have stuck regardless of how much caffeine I was consuming, but I had read a bit about caffeine being linked to miscarriage so when we decided to TTC again I stopped drinking it. I think it's an individual choice, a risk we all calculate according to our individual situation, itms. Best of luck!!
