Cycle dates help - implantation bleed?

[doddlebobs]

Is anyone good with cycle dates/theory?

My cycle used to always be 33/34 days but had never opk so don't know when ovulation tended to be.

I had mmc and surgical procedure start of April, af 28 days later, positive opk day 16 then af again day 29. This month positive opk day 19 and now on day 30 had some thick white mucous with brown spots in.

Could this be implantation bleeding?
Also how long after either opk or 'implantation' might I get an ic positive? Started at a bfn so long this morning I swear it developed evap lines whist I was watching!!

I just feel so desperate to be pregnant

@doddlebobs it's so frustrating isn't it. Implantation bleeding is normal somewhere between 7 and 12 dpo and usually pink or red in colour. Brown blood is old blood so it is possible that it's old implantation but I would think you'd have a positive test by now if so. If you've had a negative then I would prepare yourself for this not being your month. Fingers crossed that I'm wrong though!

Thanks hidcat! I think you're right. Clutching at straws here and second guessing every potential symptom so grateful for a second opinion. It's all so random really!
