Ok ladies I have only had 2 periods since having DS (still breastfeeding) & they were 40 days & 32 days. Before DS they were always 30+ days. This month I used OPKs for first time from CD10 & finally got a positive on CD20. My EWCM cleared up & I had a few twinges so presumed I ovulated CD21, which would tie in as my LP always used to be around 12 days. Anyway last night around midnight I wiped & there was red blood & still is now. I have very mild cramps. I don't have heavy or painful periods so it's hard to say it doesn't seem like a period. But I have never had a period this short ever. I must be about 4 days past ovulation which would make my LP so incredibly short Is there any chance this could be an implantation bleed??
