I've had a chemical miscarriage, bleeding started on the 22nd of this month and stopped on the 28th. I tested on the 26th and the following days and tests were negative. However today I've taken two tests and both have faint lines. I've uploaded a pic of one of the tests from today. Can hcg rise again after it has fallen? Also having right sided lower abdomen and lower back pain. But I took some buscopan and they pain has subsided a bit.
