And I've had cramping but no blood so I should be Okai...
Thank you so much...so it's still implantation even being that I'm 6 weeks...
More than likely you're getting implantation bleeding. Nothing to worry about. Just watch for cramping and bright red blood. If that happens contact your doctor asap.
As for the not being able to poop...increase your fibre and water intake as much as possible. Constipation comes and goes throughout pregnancy and the further along you are the more uncomfortable it'll get. So try your best to get it under control naturally now :-)
