Implantation bleeding?

[stillhangingon]

I'm cycle day 50 today and thinking I ovulated very very late and just had some strong cramping and immediately after went to the toilet and saw what looked like pink discharge. It looks pretty much exactly the same as when I implanted with my last pregnancy. It's so faint it just looks like discharge tinged pink. I have no idea when I ovulated because I usually have regular 28 day cycles and this one has been so long, but 11-14 days ago I had watery discharge and cramps. Could this be implantation? I really don't want to get my hopes up. When should I test? Thanks in advance

Also I started doing opks for the first time four days ago because my cycle has been all over the place and wanted to see if I was ovulating and all of them have been dark and haven't changed.

Omg! We could almost be twins, only I'm on cd24 so I haven't passed my normal 28-29days. But the last 2 cycles were off. Normal cycle 28-29 days. 20 cycle this time with a 3 day period. LH test starting cd7 with peak results. I spotted CD18-19. Today is 7 days till period(if I’m sticking to my 28-29 norm) tested LH yesterday on cd22 resulting in higher peak than the first one on cd7. All cheapie hpt are negative. So confused. Also taking Leterzole cd3-7 to induce ovulation and progesterone cd13-25 since I tested low. This is my first time using LH Testing.

Update: sent a message to my OBGYN and going off of my pregnancy history and following my normal cycle of 28-29 days, I'm technically late.
I have to go in tomorrow and get a blood pregnancy test, then another one on Wednesday and then a sonogram on Thursday. I also have to take 200mg of progesterone vaginally, every 8 hrs until we figure out if I'm pregnant or not.
