Eh, totally normal la! A lot of us mums actually went through the same thing, first trimester hormones boleh buat you feel exhausted, nauseous, or just emotionally flat, so of course the mood for intimacy goes missing lor. One of my mum friends said she felt completely turned off until second trimester sebab the exhaustion was just too much, and her husband was very understanding about it. Just communicate with your partner, make sure he knows it's the pregnancy talking and bukan because of him, and things usually pick up later on, I promise!
