Hey ladies so my pregnancy has been going by super fast the past weeks ill be 9 weeks exactly on Monday and my first appointment is the 23rd 😍 I've been seeing a lot of woman posting about sneak peak and me and my sister are so desperately wanting to find out the gender 🥺 is the sneak peak worth it? if so how much is it? or should I just ask my obgyn/midwife about a blood test to get the gender or should i wait till 14 weeks? Please help 😁🥰
