Lh rising whilst miscarrying

Nicola

I’m hitting a brick wall with my recent miscarriage at 5 weeks, I bled heavily for a few days passed the tissue very early miscarriage at 5 weeks, had 2 days of not bleeding had intercourse with hubby, started bleeding again on the 9th august and I’ve been spotting every day since, started taking ovulation tests and the LH levels are rising each day!! How? Shouldn’t they be lowering??
