Hi, I went for my 12 weeks scan today and I excepted them to tell me I am 13 weeks 2 days however they told me 12 weeks 2 days but I had 3 scans previously to this due to bleeding the first put me at 6 weeks 1 day the second put me at 7 weeks 4 days which was 1 week 2 days later and the 3rd one put me at 9 weeks 4 days which was exactly 2 weeks after the 2nd one. So today I expected to be 13 weeks 2 days but they told me I’m 12 weeks 2 days? The baby was really curled up and they couldn’t measure them properly I’m wondering if this could be why? Just because I’m wanting to book a gender reveal scan privately which u have to be 15 weeks for but now I don’t know wether to wait an extra week just in case? Has this happened to anyone else before? Can they change your due date again later on? First time pregnancy so I’m just clueless about these things lol
