4th and final IUI

I haven’t posted in a group for almost a year. My husband and I are 33 and have unexplained infertility. We are doing our 4th round of IUI in 2 weeks, this is our first round using fresh sperm. The last 3 rounds were with frozen. Im excited, nervous, freaking out. This is our last try before moving onto IVF. Im keeping positive that this cycle will work. Needing some encouragement and to chat with those going through this. Our last 3 cycles were unsucessful and we had a chemical pregnancy.
