Luteal Phase Defect?

Hi Ladies,

Please could you tell me if I might have a problem with my luteal phase this month or if anyone has similar symptoms to my own?

My previous cycles have been as follows:

Cycle 1: 29 days; Peaks 14&15 Period Started full flow 14 days after the second peak identified using cbfm
Cycle 2: 24 days; Peaks 10&11 Period started full flow 13 days after the second peak
Cycle 3: 30 days: Peaks 15& 16 Period started full flow 14 days after the second peak but had slight pink spotting on cd27 and brown 28 and 29.

This cycle Peaks10 & 11;
DP04; ewcm and wet
DP05; pink spotting then brown, slight cramping
DP06; cloudy cm; slight cramping
DP07; bit of cm
DP08; Bit of brown grainy blood like period going to start but this is only cd19!. Didn't happen all day. Also felt a bit sickly and had period like cramps
This morning bit of brown grainy blood


Should also say when I had my peaks this month I did not have any of the normal symptoms of ovulation present and thought ovulation symptoms were more present DP04


So do you think I should be expecting a very earlier period suggesing a problem with my luteal phase this month or could an implantation bleed continue for this long with these symptoms?

Your thoughts would be much appreciated

Thank you
