Had a couple OFFER to surrogate

So, my husband and I have been trying for 4 years to conceive. I started my journey on clomid and am currently on cycle 3 with it. Husbands sperm is a little low, but manageable. Alot of our friends know about our battle. We plan to try <a href="https://glowing.com/glow-fertility-program">iui</a> when my husband gets back home (he leaves this month for a pipeline). TONIGHT one of my good friends called. She and her girlfriend are wanting a baby. She threw me an offer to carry a baby for me if my husband would donate sperm for them to have a baby too. No strings attatched. Her and I work together and have become very close. Her and her girlfriend are so sweet. I felt selfish when I told her I wanted closier on whether or not I can carry my husband child. We would definitely be willing to help them out even if we are successful with our <a href="https://glowing.com/glow-fertility-program">iui</a>. And if we aren't, I would totally be okay with them carrying a baby for me, if I can't conceive. My mind is in a million places. I promised to not tell a soul, so I'm adding anonymously. Do u sound selfish? I am absolutely honored they called us. But, I can't help but ache from the wanting to carry my husbands child.
