I bought these and they taste great. A Mexican buddy of mine at school let me have one and I was hooked. The only problem I had with these is that is was the Aldama brand and not Las Sevillanas but it is still a great tasting Oblea with cajeta and I plan to buy again.
The hook effect and false BFNs. Summarised, the hook effect is when someone continuously gets negative urine and blood tests but are actually pregnant. It happens because hcg levels are too high to register and is common with mothers carrying multiples or on older woman.
Anyone with twins had the hook effect when taking hpt. So I freaked out yesterday when at 6w1d when my test was lighter. A girl in my birth month group mentioned the hook effect. So on the 4th is was darker than the control and yesterday it was light. I took another test this morning and the 100% pee test was dark again and the 50/50 with water was slightly darker than the whole pee.
