I have an arcuate uterus and I'm 4 weeks pregnant:) I did have issues getting pregnant, but that was due to my PCOS not to my uterine deformity. Basically with a regular uterus it is shaped like an upside down pear. With uterine deformities, when we were in the womb our uteruses did not fully complete and take different shapes. There's several different uterine deformities, but the arcuate uterus is one of the most mild. You basically have a small dip in the top of your uterus. Uterine deformities are rare and a lot of people, even some obgyns, are not familiar with it. They might refer to your arcuate uterus as a "heart shaped uterus" which is incorrect. A true heart shaped uterus is a bicornuate uterus which is a more serious uterine deformity. I was misdiagnosed with a bicornuate uterus for several years before I went to see a reproductive endocrinologist and he properly diagnosed me with an arcuate uterus, which is a big difference! With a bicornuate you have a much deeper split in your uterus nearly causing two separate horns which is where the term heart shape comes in. If the bicornuate split much more it would actually become a separate uterus which is where you have two completely different horns, sometimes you even have two vaginas with this uterine deformity although rare. With an arcuate uterus it is a VERY mild uterine deformity. With a bicornuate uterus I was given a slim chance of having a healthy pregnancy and baby. With an arcuate the chances are so much higher. Although you should let your healthcare provider know that you have an arcuate uterus when you're pregnant. The issues an arcuate uterus deformity could cause is the embryo implanting into the dip of your uterus which consists of dead tissue. If the baby implants there it doesn't have a healthy blood supply and will most likely end in miscarriage. If it implants correctly then you have little to worry about, towards the end of pregnancy you might be at a higher risk of early labor simply because the baby might grow out of room and start labor early. So possible bed rest might be advised. With an arcuate uterus your chances of having a healthy pregnancy and delivery are very good, hardly any less than a woman with a normal uterus.

I'm going to attach two pictures. The first picture is my uterus, an arcuate uterus. You can see there's a mild dip on the tip of the uterus. Kind of taking the shape of the letter U. In a normal uterus you would not have the dip, it would form upwards like a bubble and look like a pear shape. The bottom is a bicornuate. I'm attaching this because people might refer to your uterus as a heart shape which is incorrect. A bicornuate is a much more serious uterine deformity. Even if women have a bicornuate uterus I have read successful stories of them having healthy pregnancies. But keep in mind that early delivery is expected. Often with a bicornuate uterus the baby doesn't have room to flip around and is often breeched and requires c-sections. I'm 4 weeks pregnant with an arcuate uterus so I'll let you know how my pregnancy goes:) by the way I got pregnant from doing letrozole and an IUI, I would definitely recommend that to you since your husband has low sperm count. The success rates are better than having natural sex. We got pregnant our first IUI.

My arcuate uterus: notice the U-Shape on the top. That is what differs your uterus from being a normal uterus.

A bicornuate uterus: A more serious uterine deformity. Many women who have arcuate uteruses are often misdiagnosed with a bicornuate as many health care professionals are not used to seeing uterine deformities and are not knowledgeable. Once you study them you can notice a huge difference. This is a true heart shaped uterus because of the separation that causes the horns.
