Ok so I think my friends Lying to me 😭

So I have this friend and I told her that I was ovulating yesterday and I'm trying for a baby and she had her second baby 5 weeks ago and all of a sudden she wanted to try for another baby then last night we were talking and she told me she was gonna start trying, I woke up this morning and she told me she has the doctors as she thinks she's pregnant she told me she's had sex 2 times a both with a condom and she hasn't had a period yet since her baby was born, yet she thinks she concieved the day SHE GAVE BIRTH TO HER 2 CHILD!!! before she was born but that day I said I don't think that's possible she said her Nan conceived a baby the same way! Then I asked her for a picture of a test which she said was faint positive she said in just popping out I will when I back, so a few minuets later she sends me a picture of the test positive! Then she sends me a snapchat of her and her kid in pjs so I don't think she went out I think she looked for a old test pic, It just doesn't add up!!! She's going for a internal scan today so she says but how would she get a appointment that quickly!

UPDATE:

There's apparently 3 sacs but apparently the midwife said 1 looks like it will miscarry 😩
