Ok guys... what could this mean. I used dollar store cheapies but I hear they work just as well. I was 3 days late for AF. Got af and it was short and weird. Now I have continuous cm. HCG is neg but can a faint OPK mean anything?

Ok I have never been late always 28 days. On time like clockwork. This month, I’m 3 days late. I finally get what I thought was my period. First day I was crampy and had somewhat of a regular flow, day 2 bright pink with tons on clear stretchy cm and day brown spotting and next to nothing. This is way different than my usual 5 to 8 day period. Then immediately after the spotting I’ve had constant milky cm. 🤷🏽‍♀️. I read that It’s possible to not have enough hcg to get a pos result on the pregnancy test but opk’s can detect hcg and lh. My hubby, the kids and I are praying this is our month. O is said to be in 5 days according to Glow. Ladies please give me feed back. Thanks and blessings and baby dust to all who are TTC.
