Today I am really struggling. July 2012, on my twenty second birthday, I found out I was pregnant. My now husband and I were only together for a year at that point. I was finishing up college and we just weren’t ready. I decided to have an abortion. He didn’t really want that but supported me. Fast forward to December 2014 we decided we were ready for a baby. It didn’t happen. February 2017 we decide to see a fertility specialist. Many tests later, unexplained infertility. One medicated cycle and two IUI’s, still not pregnant. IVF will be our next step. I see my husband with babies and I just see him light up. He deserves to be a father but what if It doesn’t happen for us, what if I gave up our only shot. It’s all my fault. There has not been a day since the abortion that I did not regret It. The second I left the appointment i regretted It. I would really like some advice or guidance. And before anyone suggests adoption, that is very very expensive. Thank you in advance.
