Monday showed the baby moving and the heartbeat was great. So my bleeding was from sex. I dont know how long it is to last. I have the brown to nothing all day then its gone, then in the AM I get it light again. When I cough or sneeze I get a tugging or muscle pull in my stomach. Is it too soon to feel anything? This is my 1st and I am waiting for the results of my CVS today. I am so panicky I just want to relax but just think that something will happen. Help.
