11 DPO. Positive LH, BFN

Yare

Help!!! I had a chemical last month. BFP 7 DPO and then a chemical the next day. During that entire time, my OPKs showed positive LH levels.

Forward to this month. 11 DPO, HIGH LH levels but still negative HCG test.

I had mild cramping. I spotted super dark brown for 2 days. I NEVER spot between periods. I did it last month = chemical pregnancy. I am super emotional and have nausea all times of the day.

Has this happened to anyone? What can this be?? HEELLLPPP
