A member asked:

Is it physically possible to ovulate before hcg is zero? my hcg was 26 last thursday and i believe i got a positive lh surge.. it was extremely light then a few hours later opk was dark, then light again that evening. could that have been it?

A doctor has provided 1 answer

HCG and LH are both produced via the pituitary and have the same receptor. HCG has pituitary origin prior to pregnancy, and placental origin after. You may have ovulated, and if your period is delayed, wait 7-10 days and obtain a serum HCG level, which would indicate pregnancy.

I have been testing positive for pregnancy since Friday. My ovulation date was supposedly Feb. 27th according to my app and my last menstrual period was Feb. 13th. I went to the ER yesterday and my beta HCG was 15. Does this mean I am miscarrying?

A member asked:

Natural LH surge before hCG trigger shot or not? Is it best to time the trigger at +opk or should OPK show nearly positive for best result?
