Spotting And Alarmed!

Shae
Ok so.. At the beginning of my pregnancy at about 2 months i was spotting a little the doctor said it was ok but i needed to chill out... So i did..but now im 28 weeks it has started again.. Bt only when i use the bathroom..i asked the doc they said cpuld be because of intercourse bt the baby is healthy and doing great and i am as well.. Im still worried about this and its like it feels like i have to go to the bathroom bt its a funny feeling and that's when ik i will see light blood.. Has anyone else been through this?
