Had a misscarriage 4 weeks ago and everything to have gone normal when I went to the hospital my HCG levels was only 18 hence why I had a misscarriage and pregnant tests were negative ive done 5 tests all with a faint line. Am I pregnant again or is it still from the misscarriage. Straight after the misscarriage I didn't have a postive test... Unsure and scared and nervous. Any advice would be great.
