I will be 23 weeks on Monday....Hubby and I just had sex and I went to the bathroom and noticed light blood when I wiped. I got up and noticed grainy blood (similar to period type blood) in the bottom of the toilet. I don't have any cramps or discomfort. Nothing burns or hurts. It's been about 2 hours and the bleeding has stopped. Was never bright red blood. More of a light red or pink color. We have been having sex regularly and I haven't bleed/had spotting my entire pregnancy until now. Kinda freaking out and thinking its normal...? I call the poo OB nurse so much I don't wanna bug her again if this is  normal...anyone have any input?!
