I ve been taking the HCG injections for weight loss for 3 weeks, and I took a week off from it for my Menstrual cycle and two days before doing the injection again I had sex with my Husband, now during my 4th week I had a brown discharge for one day, and off and on slight cramping, like ovulation is constantly happening and now my vagina has a slight itch, is this normal? Could I have ovulated early and now implanting? Should I stop the injections? I have one more week left.
