3D Pregnancy Month by Month Preview
Choose buffalo or cattle and a month. See where the uterus and fetus lie — from the pelvic cavity near the vulva, over the pelvic brim, deep into the abdomen and back to the pelvic inlet before birth — and whether a hand per rectum can reach the fetus.

Fetus too small to feelSeen from the right side, head to the right. The rumen (green) fills the left abdomen, so the pregnant uterus lies to its right. Blue dashed circle: how far a hand can reach from the anus (about 70 cm). Skeleton is cow-type; layout is similar in the buffalo. Sizes and timings are typical — they vary.
Buffalo: all months at a glance
| Month | Days | Where the uterus and fetus lie | Fetus | Fetus reachable? |
|---|---|---|---|---|
| 1 | 0–30 | Uterus still in the pelvic cavity, close to the cervix — the nearest it ever lies to the vulva. | Embryo under 1 cm | too small to feel |
| 2 | 31–60 | Uterus in the pelvic cavity, at the pelvic brim. | About 3–6 cm | too small to feel |
| 3 | 61–90 | Uterus at the pelvic brim, beginning to tip forward over it. | About 10–14 cm (rat size) | within reach |
| 4 | 91–120 | Uterus over the pelvic brim, descending into the abdomen. | About 18–25 cm | within reach |
| 5 | 121–150 | Uterus in the abdomen, cervix pulled forward to or over the pelvic brim. | About 28–35 cm | hard to reach |
| 6 | 151–180 | Uterus deep on the abdominal floor — the furthest from the vulva. | About 38–48 cm | OUT of reach |
| 7 | 181–210 | Uterus fills the right ventral abdomen, still deep. | About 50–60 cm | OUT of reach |
| 8 | 211–240 | Fetus large; parts of it come back towards the pelvic inlet. | About 62–72 cm | hard to reach |
| 9 | 241–270 | Fetus fills much of the abdomen; head and forelimbs towards the pelvis. | About 75–85 cm | within reach |
| 10 | 271–310 | Fetus in front of the pelvic inlet, preparing for birth. | About 85–95 cm (calf 30–40 kg) | within reach |
