How early have you had pregnancy symptoms?

Bonny 🌈

I just found out on Monday I'm pregnant after 18 months of trying for my first. I found out at 2 weeks post ovulation but as I ovulated really early in my cycle I was only 3 weeks and 3 days pregnant. Since that morning I've been feeling very icky, breasts already growing with new veins, wet mouth, hot flashes like you wouldnt believe and so tired! How early have you experienced symptoms? Do you think i could be having twins?!?!
