Women using weight-loss jabs are being advised to stop if they are trying for a baby, have fallen pregnant or are breastfeeding.Drug safety experts in the UK say it's not known whether taking the medicines, such as Wegovy and Mounjaro, could harm an unborn baby.

The advice already appears in patient information leaflets that come with the medicines.But there are concerns that the growing popularity of 'skinny jabs' means many women aren't using the drugs safely or getting the right advice.Natasha Major, 26, started using Mounjaro to lose weight before planning to try for her third baby in a few years' time, but was shocked six weeks later to find she was pregnant. She was taking the contraceptive pill at the time.

"I have polycystic ovaries as well, so I can't get pregnant easily or quickly. So it was an even bigger shock that I had, which didn't make any sense to me," she says.She then worried she could be harming the baby or it wouldn't develop properly, so she rang her GP for advice, who told her to stop taking it.

"We're over the initial shock now and really happy, just wasn't expected," she says.

"The last injection I took, I found out about the pregnancy three hours later and haven't taken it since then.Another Isro experiment involves growing three strains of microalgae which could be used as food, fuel or even in life support systems and this will help identify the most suitable ones for growing in microgravity, she says.

The Isro projects would also investigate how tardigrades - micro-animals on Earth that can survive extreme environments - would fare in space."The project will examine the revival of dormant tardigrades, count the number of eggs laid and hatched during a mission, and compare space-flown versus ground control populations," Ms Mitra says.

The other experiments aim to identify how muscle loss occurs in space and how it can be treated; and the physical and cognitive impact of using computer screens in microgravity."The research will study how gaze fixation and rapid eye movements are affected by being in space, and how this may affect an astronaut's stress and wellbeing. The results could influence future spacecraft computer design and interaction," she says.
