Ectopic pregnancies question

Lovely • IG: TTC #4. Sept 2014 tubal reversal. Feb 2016 HSG: blocked tubes. May 2016 IVF: failed. Aug 2016 BFP turned to 4th loss
Hi ladies, I got a tubal reversal done and now I'm at risk for ectopic pregnancy. If any of you have had one, I'm sorry, but can you share with me what are symptoms? Did you get an ultrasound right away from doc?
