Feeling bad for being frustrated..

So my baby #1 is almost 3, and I got pregnant with him pretty much right after I went off BC...so I figured getting pregnant with baby #2 would be easy....not so much!!! I went off my pill end of May, I got one regular period and then got pregnant right away again, but after two weeks of pain and bleeding, and being diagnosed with a MC, we found out I actually had an ectopic pregnancy, and I had to have laparoscopic surgery. The doc was able to save my tube, but now I'm not getting pregnant..and I feel like there must be something wrong now.  I feel guilty because there are so many people who have trouble conceiving just one baby, and I already have a child and I feel I should be thankful for that (which I am) and stop whining, but it's so hard. I'm due for AF 11/26, took a test today and it was neg, (I know, super early, but I'm impatient!) I don't feel pregnant at all..But I had no symptoms with my first either....this is the first month I did an ovulation test, and we definitely tried at the right times, so I'm really hoping.it doesn't help that pretty much every person I know is pregnant right now. Ugh, just had to vent, feel like I'm losing my mind!!
