Hi, I'm an old member and haven't been around in a while, I'm after some advice / reassurance if I can please

I'm wanting to know if anyone has experienced pregnancy symptoms super early, like 1 day after possible conception?

I am not ttc, I don't have my cycle back since having DS2 (who has just turned 1), but today I have a terrible metallic taste in my mouth and a sore throat, however the sore throat is not like a cold/flu type of sore throat, it's quite different, like how it feels after something's been lodged in your throat. This was the first symptom I had when I fell pregnant with DS1 and the main reason I'm asking today.

I have not been using any contraception in a couple of months and planned on having the depo needle on Friday. Should I postpone this?

I know this all sounds pretty ridiculous, but I thought I'd ask anyway just to see if there are any other super early symptom stories out there?

Thanks everyone
