Blazing BFP accompanied with cramps

Anyone test around 13 DPO and get a blazing BFP but then start to get cramps? My period is due in 2 days and I’m terrified something is going to happen, I always hear of these chemical pregnancies and I’m so scared! I heard cramping is normal and I’m also getting some pimples and stuff but I know PMS symptoms can be the same as early pregnancy.
