From the information you have provided it is impossibe to give an assurance, obviously it is impossible to predict how your next pregnancy would be. After an ectopic there is a high chance that any subsequent pregnancy would be an ectopic as well. So please get an ultrasound done to see that this pregnancy is in the uterus. If it is ok, ideally you should continue but if you decide to abort you should remember that your next pregancy (as and when you want it) may be ectopic and you may regret aborting this one then. I am not suggesting that if you abort this one then you will not conceive again or you will only have ectopic pregnancies only. But there is always a chance that it may happen. The chance of this one or any other pregnancy you have being an ectopic is about 10 % (meaning thereby that 90% would be in the uterus and normally placed) so please take a decision consciously and keeping all this in mind.
