What is happening to my body?

21 Oct 2019, Dr confirmkan no sac &  heartbeat, my uterine line pun nampak thinning.
With no extreme cramps, or heavy bleed, am still spotting and faint bleeding up to this date.

21 Oct 2019, did UPT again (31dp3dt) still double lines. Might be hCG hormones still not out of the system.

27 Oct 2019, did another UPT (37dp3dt) to double check hCG. Yep, still double.

2 Nov 2019, another UPT (43dp3dt) still double line.

No heavy bleeding, no blood clot. Nothing.

Note: Husband suggested to give another check up to double confirm. But am afraid to face bitter truth, twice.
