Hello Thanks for writing to us with your health concern. You need not worry about the LEEP healing. An acute cold , cough and URTI will not interfere with its healing. One acute episode of illness will not drastically lower your immunity at all. LEEP has to heal in a few weeks time, and it will. So stop worrying on that count. Regarding conception, please avoid sexual activity for atleast 6 weeks following LEEP. Also, after the 6 weeks period is over, then continue using condoms to avoid further cervical erosions or infections for atleast 3 months. Please have a review examination with a gynaecologist after 3 months of LEEP, in order to have a proper per speculum and per vaginum examination. This will confirm that the cervix and the LEEP has healed properly. After that you can definitely continue to try naturally for conception. Just that there might be anticipated difficulties in normal labour and delivery. A C section might be required to deliver the child. All the best. Take care.
