It is not uncommon to experience discomfort, pain, or itching during sex while pregnant. The growing uterus puts pressure on the pelvic area, leading to a feeling of heaviness or a "bump" sensation. Additionally, increased blood flow to the genital area can cause sensitivity and itching. To find relief, try experimenting with different positions that alleviate pressure on the abdomen. Communicate openly with your partner about any discomfort you're experiencing and consider using lubrication to reduce friction. If the pain or itching persists or worsens, consult your healthcare provider for further evaluation and guidance.
