Confused ladies

Yesterday morning I got my peak lh, been doing the deed the last week everyday, I had really bad pains yesterday that I put down to ov, however today I've started a very bright red bleed as if af has arrived early. Any ideas? Heard of ovulation spotting but its like the start of my period and only on cd17 of my usual 31 day cycle 😕 Its always when i feel like im getting somewhere, theres a bump in the road 🤦‍♀️
