Aww Chintaria absolutely felt the same on all counts, we were so elated our long journey ended with the happy outcome of Teddy, and that was a beautiful line underneath it all.. Getting pregnant again unexpectedly on the pill, was a shock, and was really wierd to be so confused and negative about it, then just as we started to come round to the idea, we lost it, and exactly like you was so angry in a way that my last experience of pregnancy ended up being a negative one, instead of ending with a positive one.. Felt clouded and a bit cheated of what had previously been our happy ending.. Totally get how you feel, and with mine being ectopic too, the health risk and reality of putting my poor body through a 10th pregnancy, made the decision of vasectomy an absolute definite.. All those emotions have now faded, and I do feel that last one just wasn't meant to be, it would of actually been due next week... But like you, we've our gorgeous girl and beautiful boy, and are really happy to just be our family of 4.. 
All those raw emotions will fade, I promise you, as your darling little babies grow and go through all their various delightful little stages.. Teddy's really starting to talk and it's amazing.. But, yes had to post to say totally understand where you're coming from, but it will get better
