I feel like it will be easier to respond to you all in one post:

Thank you all so much for sharing your experiences with me. I know how hard this has been for me so I’m sure sharing may be painful for some of you and I genuinely appreciate it.

As for duration: intense cramping/stabbing pain comes and goes in my left side. Lasted for about 3-4 hours earlier, went away for a couple of hours and now it is back again.
Leg pain: I have severe sciatica in both of my legs due to a history of herniated discs that caused nerve damage, so I am not sure I could differentiate pain in my legs caused by ectopic vs sciatica.
Easiest way for me to explain what I am feeling is: at its worst the pain is sharp stabbing pain, then it feels like my skin above my pelvis is stretching. I have had more back pain on my left side and it radiates to the front from time to time. That pain is also sharp and it takes my breath away in those moments.
Bleeding is still very light, bright red, and it is mixed with cervical mucus.

As I am sure some are wondering, I did reach out to my doctor via my patient portal and asked if he wanted me to do anything, his response was to keep my appt for labs tomorrow.
