So last year I lost two babies from a different partner that was all wrong for me. The loss of the babies was fairly close together but I definitely do not have infertility issues. I have two beautiful children currently that I had no trouble conceiving. My new husband and I have been trying for a few months now and I haven’t gotten pregnant. I feel so frustrated because I’ve gotten pregnant so easily in the past but now it’s just not happening. I’ve never had to try so hard to get pregnant and I’m only 27 and healthy. Possibly the two lost babies effecting my fertility? It’s now been over a year since those incidents.
