Happy Anniversary, Jill Duggar and Derick Dillard! The former Counting On stars are celebrating four years as a married couple today, and in honor of the special occasion, Jill shared a sweet snap with her main man on Instagram. "I'm blessed beyond measure to have you as my hubby!" she captioned the shot in her wedding dress. Watch the video above for the rest of her message — and to see their rare wedding day shot!

Fans joined in to celebrate their day, with one person writing, "It seems like just yesterday I was crying watching your wedding. Happy Anniversary!" Another added, "Love this picture!! Happy Anniversary. Hope you have a great day celebrating your love," and a third chimed in, "Four years, wow. Where are the four babies?" Ouch, we feel the shade.

Jill comes from a conservative family of 21 who doesn't believe in birth control. Her mother, Michelle, was on contraception following the birth of her oldest child, only to find out she was pregnant. After losing the baby, she and Jim Bob attributed the miscarriage to birth control.

"As conservative Christians, we believe every life is sacred, even the life of the unborn. Due to our lack of knowledge, we destroyed the precious life of our unborn child. We prayed and studied the Bible and found a host of references that told us God considered children a gift, a blessing, and a reward," they explained. "Yet we had considered having another child an inconvenience during that busy time in our lives, and we had taken steps to prevent it from happening."

As a result, fans have been speculating if Jill is pregnant with baby No. 3. Most recently, Derick shared a strange photo with of Jill from her chest up — which had many convinced she was hiding a bump. "Is Jilly pregnant?" asked a fan. Another said, "I think so. All her pics hide the belly." Well, if it's true, that would be one exciting anniversary gift!
