Possible signs of pregnancy... or irregular cycle (and irregular chart!) imput would be appreciated!

So this month is weird. My char is doing things it has never done before... which is odd for me since I have your pretty traditional 28 day cycle with your typical temp rise and predictable ovulation timing.

Anyways, here is my chart:

On cycle day 15 my partner and I had unprotected sex (it was an oops but a bit of a cheeky oops ;) I had yet to experience a temp rise at this time but did notice creamy cm for the past several days (I often get a lot of creamy cm rather than egg white at my fertile stage)

It's now day 19 of my cycle and I still have not experienced a temp rise of any significance. I assumed that this meant that perhaps for the first time since charting I did not ovulate.

Yesterday I noticed very mild cramps and at the end of the day when I had a shower, I noticed some spotting of (sorry tmi) dark brownish blood along with some stretchy mucous.

So... questions

1) Is it possible I did ovulate with my chart or is it highly unlikely?

2) Is it possible that I experienced implantation bleeding yesterday (aproximately 1 week after unprotected sex on a day that is usually my "peak fertility day" ?

OR

3)Is it more likely (due to the status of my chart etc) that I am experiencing a wacky cycle and there is little to no chance I ovulated let alone be pregnant and this is just irregular spotting (though I never experience this since removing all forms of BC from my body)

I know no one can give me an exact or definite answer but I am hoping that some people might have anecdotal evidence either way about what might be happening.

Thank you for any input!

cheers

It sounds like you're experiencing breakthrough bleeding.  It sometimes happens, usually in a longer cycle with delayed ovulation.  What happens is that the lining of the uterus builds up so much that it cannot be maintained by estrogen alone (without progesterone, which will be dominant post-ovulation).  Women experiencing this usually just notice a tiny bit of blood in very fertile mucus just before ovulation, though in some cases, it is so much that it appears to be a whole period for several days.  It's likely that you'll ovulate very soon, and then the spotting will go away.
