Endometriosis Support Group
Endometriosis is a common medical condition where the tissue lining the uterus is found outside of the uterus, typically affecting other organs in the pelvis. The condition can lead to serious health problems, primarily pain and infertility. A major symptom of endometriosis is pain, mostly in the lower abdomen, lower back, and pelvic area.
I didn't have implantation bleeding when I got pregnant, however I do know that the implantation bleeding can be on a completely different cycle than your normal period.
I don't want to scare you either but endo can sometimes cause ectopic pregnancy if it is on your tubes. I had one and I cramped and spotted. If your cramping gets worse, you might want to check that out.
Sometimes ectopic pregnancies don't show on a regular home pregnancy test either, so just listen to your body.
Keep trying, and don't give up hope. :0)
