Pregnant???

Ok so my husband and I tried for 3 years before we finally got out BFP. However the joy was short lived and at 9 wks found out the baby was ectopic. I had to have emergency surgery but they were able to save my tube. This all happen this past October. My cycles have normalized since and so this last month with my doctor's approval we began to try again. Now here I am 5 days late. I took a test the day my period was due and it was negative. I am so scared because what if it is another ectopic and that is why it is not showing yet. Would love any advice. Has anyone else been in a situation similar?
