Could it have been implantation bleeding?

My cycle, since I miscarried in June, has been exactly 25 days,,,except last month. It came three days late making it a regular 28 day cycle, I am trying to conceive so...at the time was hoping that it meant I was pregnant. So now I am confused as to what day I would be ovulating and such. Anyways, I had unprotected sex twice on day 9 of my cycle, I woke up on day 19 of my cycle, and when i wiped I had just a very tiny bit (maybe a few drops) of red blood when I wiped. I checked myself to see if I had maybe gotten a scratch or cut down there that it may have come from but I did not find any. I wiped clear the rest of the day. Could this have been implantation bleeding? I am not sure if it could really be that light but I have never had any kind of spotting before a period in my life and my period shouldn't be due for maybe another week.

Hi!
If from the date of your spotting or light bleed, your next period date is about 2 weeks away, then that could have been ovulation bleed. If periods are just a week away, then that can be implantation bleed. Wait until your due date, and if you miss your periods take a test and see.  Take care!
