Period 8 DPO.. is it possible to have a short luteal phase?

[FutureMrsD]

If someone can help I would be really appreciative..
First monthly using OPKs, had a positive Saturday morning and evening so guessing I ovulated on the Sunday.
Today I have some brown spotting when I wipe (sorry TMI), so I guess I am about to expect AF imminently..
Normal AF symptoms have been cramps and spots but have also had back ache, very grumpy and tender breasts which is not normal for me.
Also, my last 2 cycles have been 51/52 days and I am currently on CD 31, so 20 days early.
If this is AF and I have a short luteal phase, surely this is really bad news for TTC? 😕
Thank you as always ladies x

I had brown discharge and I got my BFP could be implantation bleeding

Thats good news @bunnieboo91, thanks for your reply!
How long do you think I should leave it before I test? How many dpo were you had the discharge? X

I had it around 5/7 DPO
Always test the day your period is actually do for the HCG hormone to be strong enough to detect. I wish you all the best

It could be implantation bleeding!
Also, I have a 9/10 day LP and have conceived 3 times so far.
