Hopeless

I got pregnant with my daughter after rltrying for 8 months, when she was 7 months old I got a copper IUD (Paragard) 13 months later (May, 2015) I had it removed to try for our second. So far it has been 5 months with no success. When I had it taken out I was on my period, June I had a normal period, July I completely skipped, August and September were exactly 31 days apart and now here we are in October and it's been 33-34 days since my last cycle. I've taken 2 test (both negative) and am starting to feel really hopeless that I'll get pregnant again. If anyone has any positive advice or encouraging words, I'd more than appreciate them. TIA!
