The 14-year-old was last seen at around 10.20am on Saturday 1 September in the Burgess Road area.
Officers have conducted a number of enquiries to locate Monica, and continue to do so, but are also asking the public to keep an eye out for her as we are growing increasingly concerned for her welfare.
Monica is described as:
5ft 6ins tall
Long strawberry blond/ginger hair
She may possibly be wearing a burgundy coloured hoodie.
Monica has links to Southampton and Basingstoke in Hampshire, but also Blackpool in Lancashire, Bracknell in Berkshire, and Walsall in the West Midlands, so we are asking people in these areas to help share our appeals too.
If you have seen Monica, or have any information relating to her whereabouts, please call police on 101 quoting 44180331231.
