Hi there emmakay!!
Hope you're doing ok! Thought I would share my experience!
A couple of years ago we were trying for baby number 2 and I was two weeks overdue before I even got a positive test! Actually changed my doc coz I had gone in 1 wk late and he was of no help at all. New doc sent me for blood hcgs and a scan. hcg in blood confirmed pregnancy, but levels were low and not rising properly. Scan found no sign of a pregnancy. I was devastated. Was sent to hospital coz they thought it was ectopic too. Ended up miscarrarying so they think it was a chemical pregnancy. Was horrible being in limbo tho, knowing i was preg, but also not knowing what was going on!!
Really hope you get a better result than I did, but thought i would tell what happened to me.
On a positive note, got pregnant the very next month and had a beautiful healthy daughter last april.
I recommend you go in for a blood test if you can, to see if your hcg levels confirm the pregnancy, and to check that they are doubling every 2-3 days.
Wishing you all the best, i know i got to the point where i just wanted to know either way. GOOD LUCK!
