Am I imaging things? helppp!

[faeriemum]

hi, im new so please bare with me...
i have a 17month old son so am aware of signs of pregnancy .....
i had unprotected sex 3 weeks ago (4weeks tuesday) i had the morning after pill the day after..
i bled a little the day after the pill..but nothing since....i have been having alot of pregnancy signs like cramps, vaginal discharge, tender nipples, nausea, gone off food and headaches...
i had all of these with my ds...i am utterly convinced that i am pregnant and was due period 3 days ago....had nothing...
the problem is i took a pregnancy test today which is negative....im so upset!
i am starting to think that i have made a mountain out of a mole hill and imagined all of my symptoms....i have a gut feeling that i am pregnant....was 3 weeks too early for test? do u think ive gone raving bonkers?
can the morning after pill fail? i wish i never took it!

WELL YOU SOUND BONKERS IN A NORMAL WAY TO ME [SMILE] oops didnt mean to shout..

the morning after pill doesnt always do what you want ot to do...
dont know if thats good news or not xx

and im weeing 100 times a day....

I took the morning after pill, and ended up with identical twin daughters.........how ironic.

I have often wondered if it was the morning after pill that caused me to have twins.

Do you still have the leaflet that came with the pill, I think the side effects of it are a few of your symptoms.

yes nausea is a symptom, but nearly 4 weeks later and 3 dayslate period...im think pill would have worn off by now.
