Implantation bleeding 3 weeks after possible conception?
So me and my partner did the 'deed' on November 1st, it is now November 23rd. My period is due today, I woke up with very very slight dull cramps and thought well this is the start of it but when I went to the loo, it was just very light pale pink, as the day has gone on, it's just very pale spotting. i have never in my life had spotting. my usual periods (even from day one) is usually very very heavy clots and severe cramps to the point I'm usually almost throwing up from the pain. I've never had a period that's just spotting and dull cramps.. so I guess my question is, is it possible that it's implantation bleeding/cramps? I did test a week ago but it was negative, which I kind of expected anyway so decided I'd wait until a missed period before testing again. Is it even possible to have implantation bleeding 3 weeks after possible conception? i always thought it was within the first week to 2 2 weeks?
