Feeling disheartened

Been having crazy symptoms all week and did a test yesterday at 11dpo and got a faint positive, strong enough that I can see it without squinting told hubby and he said we will go to the docs and get it confirmed...woke up this morning to the smallest amount of pink blood on the tp and I thought aw must be implantation bleed as there was nothing all day.....then boom this evening I had to run to the bathroom with a slightly heavy blood flow which never happens when I start af (also affect not due for atleast another 4 days but the past 2 months it's been like 10 days late) so think I have suffered from a chemical pregnancy and man it sucks......been ttc about 18 months now....it is so hard and I'm so upset... don't wanna talk about it to family as right now it hurts too much....why is this so difficult 😢😢
