Spotting from 7-13DPO

[notthehippopotamus]

Just hoping to draw on your combined expertise, ladies. :)

DH and I are TTC #1 and have only been actively TTC for 2 cycles, but I've been off the pill for 8. I've been charting and my cycles had settled down nicely to 28 days with a 13-day LP.

Now I've had a very odd cycle: OV CD14 as normal followed by a clear thermal shift, then spotting from 7dpo with a little cramping on one side (more like OV pains than AF cramps). At first I thought implantation bleeding, and got a bit hopeful. However, the spotting continued for another 6 days, although temp stayed up. Temp then dipped on CD 27 (13DPO) and AF turned up very heavy. :(

I've never had spotting in the LP before, other than the day of temp dip before AF properly arrives.

Has anyone had anything similar? If it wasn't implantation bleeding, any ideas what it might have been? I don't want to over-react so wasn't planning on going to see my GP about it unless it happens again this cycle. Grateful for any experiences or ideas you might have to share :)

I don't know if it could have been a very early missed miscarriage?

Don't take my word for that, I'm sure the combined Mumsnet wisdom will come up with an informed answer.

There is a thread for spotters somewhere. Does your spotting last until your period?

As a rule I spot for the days before AF turns up, although sometimes I get spotting, then nothing, then AF.
I've been taking vitamin b this cycle as I've heard it can help.

Thank you ladies! I've never had any spotting before other than just one day before AF, and only when temp dips. This was from 7dpo every day for a week until AF arrived, even though temp stayed up until the day AF arrived, which is why it seemed odd.

I did get some vitamin B when I first came off the pill as my LP was a bit short, and it seemed to help with that, but I'd got a bit careless about taking it so I'll try to do so more regularly - thanks Pipbin! :)
