Hey Jojo,
i can understand how you feel, kinda. I had two BFP's last week after 2 years of TTC, and then starting bleeding heavily today. 6 hours at a&e confirmed i was no longer pregnant. The lady doc suggested that my BFP's earlier were incorrect and that i prob wasn't +ve inthe first place (she had no tact btw). Made me boil inside cos i know what i saw, as did my husband, best friend and sister.
My insides feel pretty much the same as yours, it feels so much worse than 'just a normal period'
I went to my GP earlier and he said that there's no reason why a test should show positive if it isn't, and concluded that conception had happened.
I think that if you've planned it or not, it's still a horrid shock to the system and leaves you feeling completely empty and numb.
You have every right to feel how you do, so don't let yourself feel guilty for feeling what comes naturally.
I hope your physical pain subsides soon, and i hope you work through your feelings of confusion. I have no idea how to do that, as i'm going from confused, to angry and back to numb myself.
