Faint O test then nothing 6 days later faint O test again?

Hi girls, last month I was on an assisted cycle had an early MC delayed AF by 2 days. I am on my own this cycle, I started testing on day 7 and got a faint line day 8 even fainter, so I thought maybe I had hormones still in my system from last cycle??? Continued to test !!get to day 13 faint test again, day 14 am day14 pm full moon and an eclipse thought this is a good sign day 15am still faint test although a bit darker. I have used these tests before and found them to be reliable cycle is 21-24 days by myself so day 15 and not a positive test I'm not sure what to think!!!!!Is it possible to O twice in a cycle?? Do you think I have'nt O yet or could I be BFP????
I had CM from start of cycle,really great CM from about day 12, now stretchy CM has gone, but still have lots of thick white CM. Have been BDing loads and am getting over it but not sure where we are, am afraid that O has been delayed by MC even if it was early. Any thoughts would be helpful.

Maybe your cycle will be a little out of sorts this time round and ovulate later. Sometimes especially after miscarriage this can happen and all will be back to normal next cycle hopefully. My last cycle was like that and ended up o'ing on cd 32 which is really late as my cycle is usally about 32 to 34 days long. Thanfully this cycle is back to normal and I o'ed alot earlier. I would just keep testing especially is they have started to get darker. (I have heard that an opk test shows up positive when you are pregnant).
Hope all works out!

Thanks Cherie, not so great at the waiting game. But.....no choices, I guess.
