My husband and I were trying to conceive for almost two years

My husband and I were trying to conceive for almost two years. We have one son who is 6 years old. We have been diagnosed with unexplained secondary infertility. We have done 4 medicated <a href="">IUI</a> cucles (Gonal F and Ovitrelle) with no success. We have decided to move on to <a href="">IVF</a> as our last resort. Our <a href="">IVF</a> schedule was delayed for two months because my doctor was abroad and his clinic was closed, and we thought it is a good chance for us to take a rest for a while and get prepared for <a href="">IVF</a>. My last period was May 28th, and I was waiting for the next period (approx on June 23rd) to come so that we start with injections and the preparations for the <a href="">IVF</a>. However, my period was late, I thought nothing of it as we really weren't trying that month and were taking it so easy, and thought maybe it will come the next morning since I had some cramps and headache (usual pms symptoms for me). Next morning also was nothing, I waited three additional days afraid of taking another pregnancy test fearing the results I used to see every single month for the past two years. This was until I woke up on Sunday, June 26th with nausea and dizziness and then decided to take a test! For my surprise it was a positive and I could see a second line in two minutes! I couldn't believe my eyes, I sat on the floor and the result in front of me crying and calling for my husband!! I took a digital test and it said "Pregnant 1-2"!!!
​All I want to say is that there is hope no matter what happens God is great and will never forget anyone with his blessings! Be Patient and take it easy!
