There is only a small possibility of becoming pregnant soon after a miscarriage because the reproductive system needs time to start another cycle. The body needs 1-2 weeks to clear the remaining hCG. hCG stimulates the yellow body to produce estrogen and progesterone. Both hormones block the hypothalamus to start another cycle. When hCG is cleared, the hypothalamus will start to produce Gn-RH that stimulate the pituitary gland to produce FSH and LH. It is the FSH and LH that, in turhn, stimulate the ovaries to prepare another egg-cell for ovulation. The symptoms that you’ve described are typical of a urinary-genital infection. The uterus is vulnerable to infections after miscarriage. Nonetheless, you can take a pregnancy test but you have to go to your gynecologist to treat and diagnose a possible genital/urinary infection.
