What happens if you drink caffeine in the first trimester?
During pregnancy, the maximum limit of caffeine intake recommended is 200 mg/day (about two cups of coffee) [5,6]. This is because maternal caffeine consumption has been associated with miscarriage, stillbirth, low birth weight or small for gestational age, and with overweight or obese offspring [7,8]. Over-consumption of caffeine (more than 200mg daily) is linked to miscarriage, low birth-weight and fetal growth restriction, but many women are unaware what 200mg represents in real life.
What causes miscarriage in early pregnancy?
Most miscarriages happen because the unborn baby doesn’t develop properly. About half to two-thirds of miscarriages in the first trimester are linked with extra or missing chromosomes. Chromosomes are structures in each cell that contain genes, the instructions for how people look and function. Causes and Treatments for Missed Miscarriage Chromosomal abnormalities in the fetus are the most often cause of missed miscarriages, since these abnormalities do not allow the pregnancy to develop. If a miscarriage has occurred early in pregnancy, you will often be able to expel the pregnancy tissue naturally.
What week is the highest risk of miscarriage?
Your chance of miscarriage is highest when you first find out you’re pregnant — around week 3 or 4. During weeks 3 and 4 of pregnancy, the miscarriage rate is roughly 25% to 33% of all pregnancies. After week 4, the rate drops to 15% to 20% between weeks 5 and 6. More than 80% of miscarriages happen during the first trimester or by the end of the 14th week.
