Annoying friend

My friend found out she's pregnant. I'm also pregnant, she is 8 weeks along and I'm 12 weeks along. She texts me a week ago and tells me "I swear I feel like baby is bigger" I asked her why and she tells me "ultrasounds" okay. Anyways, ever since she's been trying to get pregnant she's been trying to make this whole thing a competition! Idk why? I've been ignoring her lately. Today she told me she's actually 13 weeks along. Like what how? Her baby was measured 8 weeks and she tells me her doctor made a mistake? 🤷🏻‍♀️😂 omg. How can I cut this girl out of my life without being rude and causing drama. I hope she knows ultrasounds measure the sizing of her baby and can't be false. no way she can be 13 weeks if she was 6 weeks when she found out and 7 when she went to her ultrasound last week. 🤷🏻‍♀️
