Gestational sac with no fetal pole
My question is about a gestational and yolk sac with no fetal pole. I am about 4 weeks pregnant. My hcg level was at 7,000. Ive had 2 ultrasounds because they thought with the first one I had an ectopic pregnancy, she could only see the yolk sac. But that was ruled out. My question is, when should I start to get concerned about there not being a fetal pole or heart beat. Some women have said wait until at least the 8th week. If nothing is found then, my pregnancy is probably not viable. I am just to early to see anything? Is my hcg level where it should be? When should I hear a heart beat? With no fetal pole should I be concerned about a miscarraige?Also before I took a pregnancy test or missed my period I was already having symptoms such as fatigue, queasy stomach and very tender swollen breast, that's how I knew personally I was pregnant. I just don't know if Im actually 4 weeks, if I was already having symptoms.I feel further along. My stomach is already poping out and I was very active, very fit, so my stomach was FLAT! This will be my first pregnancy, so Im a little worried and confused about everything. I hope someone can help me with as much information as possible. Thanks.
