Is It Normal To Bleed When You Exercise?

Hi I am 19 had a baby 6 months ago..... Normal birth healthy baby 7pounds 5 he weighed. I bleed for 14 weeks after birth but doctor give tablet to reduce bleeding to give me a break...so far so good but then I started having problems when I exercise I bleed everytime I exercise no matter weather it 5 mins on the bike or a full work out I also had problems going toilet so he give me lactose medicine to make me go wasnt that affected and I still am bleeding when I exercise. I am scared in case its something serious so no matter how small you may think it is go doctors and check.!!! Worried mother

You did not say whether you are on your period or not. If you are you will bleed a lot heavier as you get the blood flowing through your body a lot faster and thus make your period heavier when you exercize. You also need to be more specific with your question as no one really knows whats going on with you except that you bleed when you exercize
