It’s really tough. My twin pregnancy was my first so I had nothing to compare it to but found I struggled a lot more than people I knew of the same gestation carrying just one baby. I had to scale back a lot In the last month or so. My advice would be to rest where you can. The tiredness wasn’t linear for me, some days were better than others energy wise so just take each day as it comes. My twins are one week old now and it’s already so amazing so it’s worth it! 😊
My sickness was so much worse, felt bigger sooner, much sorer boobs and horrendous heartburn. I finally started to feel more human at around 16 weeks. I did have some antisickness but they just have different symptoms. Omeprazole really helped with the heartburn but apart from that it was a case of riding it out ….until third trimester hit and now my pelvis feels like it’s fallen apart!
