Pippa Middleton announced this week聽that she is聽expecting her first child聽with husband聽James Matthews, confirming聽reports that initially started circulating聽in April. Middleton, the younger聽sister of Catherine, Duchess of Cambridge, wrote about her first trimester in her latest column for Waitrose, a UK food and lifestyle magazine.

鈥淚 was lucky to pass the 12-week scan without suffering from morning sickness,鈥 she wrote, according to聽multiple outlets including People. 鈥淭hat meant I was able to carry on as normal.鈥

Middleton鈥檚 sister, Duchess Kate, famously suffered from a condition called hyperemesis gravidarum during all three of her pregnancies. The condition causes severe nausea and sickness, and Kate was forced to cancel several royal engagements as a result of her symptoms. Fortunately, her younger sibling did not suffer the same fate.

In fact, Middleton聽has been able to maintain聽her fitness routine while expecting, although she has scaled back a bit to accommodate what works best for both her and聽her unborn baby.

鈥淲hen I learned the happy news that I was pregnant, I realized I needed to adjust my normal 4-to-5-day-a-week routine and find a way of continuing my exercise safely throughout the three trimesters,鈥 she wrote in her column. 鈥淸I] have looked at loads of books and websites on exercise during pregnancy but have been disappointed by the limited technical information on what you can and can鈥檛 do. I found that particularly so during the riskier first trimester.鈥

Middleton聽shared some of聽her go-to moves of late, including lower-impact but strength-building聽moves such as lunges, squats, and reverse flyers, which she supplements with hand weights.

Reports of聽Middleton鈥檚聽pregnancy first started circulating just days before Duchess Kate and Prince William welcomed聽their聽third child, Louis Arthur Charles, but this is the first time she has commented on it publicly. Congrats to the growing family!
