My sympathy for the tough times. You could wait another week before testing, or run a couple of tests a week apart. A strong early positive test would reduce the chance of ectopic, which typically has a slow rise in hCG hormone. A series of blood tests showing a slow rise in hCG would raise concerns. An ultrasound at the right time would confirm. You might look for a doctor office that would help with this so you could stay clear of the hospital. Good luck!
I am really sorry to hear you had an ectopic pregnancy. I have read that this really barely increases the odds of it occurring again. It increases the odds by a mere 15 percent which isn't zero but not a lot too. Most likely, you will conceive and have a traditional, healthy pregnancy after the ectopic because the odds are in your favor to do so. Best of luck to you!
