LH surge just before period?? 😮

Its CD 28 for me. Right now in TWW, probably on 8-9DPO.

As i had some left over OPKs i thought why not test, and this happened. The test line is so much darker than control line.

I was wondering if any of u tested with OPKs and got surge this late? could it be picking HCGs? I don't want to test using hpt till late of AF. I can't face to see a negative on it. :(

My cycle is about 33 days long.

Did any of u got a surge right before period and ended up being pregnant? 😁😜

UPDATE ....

CD 29 opk with second morning urine.
