Hi girls, I'm 6 obstetric weeks. I saw the doctor and had an hCG test — everything is normal, but they still prescribed Antibact suppositories for 8 days, Utrogestan morning and evening, Rotobiotic tablets 3 times a day and vitamins. I've been taking all this for three days. Today I started having strong pulling pains in my abdomen and a little thin brown discharge. I'm very worried. Has anyone experienced this?
