This is why poas before AF is due is self torture that we do to ourselve because it offers abiguous results... there can be DAYS of negatives before getting a positive on say 13dpo! So don't let it STEAL and ROB you of the happiness you've had achieved again. If it gets you this horribly down then do not test until like a day before af is due. It's a FREAK OF NATURE when women get a + 8dpo, honestly I think they miscalculated when they ovulated because implantation doesn't take place until 7-12 (or MORE) DPO!
So do NOT let this rule you, do NOT let it take away the BEST of you... it's too early honestly hon... it's not fair to be tortured like this so step away from peesticks for a few days (easier said than done, I know, btdt)
I wish the BEST

for you, but take it easy on yourself and leave the poas for a few+ days away from now.
