tell me to safe to have sex!!!

Ashley
I'm 28 weeks today and have not had sex throughout this whole pregnancy. At 5 weeks I was bleeding(progesterone was low) but got pills but I'm so scared to have sex because I might spot and cramp from it. I'm a first time mom and just thinking omg blood is bad...please reassure me it is fine and I won't lose my baby if I have sex. My poor hubby lol
