2 positive, 2 negative - pls read description x

So I’ve had 2 at home pregnancy tests come back positive (clear blue & first response) and then I’ve had another first response and a clear blue digital come back negative. I’ve sent off a urine sample to my doctors to test and I’m just waiting on the results but I’m so scared. Me and my partner got so excited when we saw the positives and now we really don’t know what to think. Still no sign of AF and I’m 16 days late today. (I’m never late).

Has this happened to anyone else and if so, did you end up being pregnant or not??
