How far into your pregnancy can it become ectopic? I am experiencing a lot of pain. I think it is a combination of gas and my fibroids, however I have a firm lump on my right side. I don't know if it is the baby or if it is something else. I have had a lot of pain all weekend. I think I am suffering with constipation, but when I finally use the restroom, I don't get relief. I am five months pregnant and this will be my first full term pregnancy. I am nervous as I am 37yrs. old and considered high risk. I am already in fear and doubtful about having the amniocentesis. What could be causing this constant pain?
