Question: 5 weeks 1 Day

Pamela • Marine wife 💍 Expecting baby #4. ❤️
Hi everyone!  I'm currently 5 weeks and 1 day. I found out I was pregnant on Jan 15 with with a home pregnancy test & the doc confirmed it just last Tuesday the 20th. I'll be having my first prenatal appt on the 28th. Although I am still very early & expecting our 4th child - I seem a little bigger. I'm not sure if it's just the bloating but even during the early hours of the morning, I'll notice my stomach start to budge out a little through my shirt. 
I've always been athletic & have continued to workout with each pregnancy.  My periods have been regular. I did get a LEEP done in September but even with that, my periods still came around the same time I would expect them. 
Am I the only one experiencing this?  I know all pregnancies are different  but I've never had to experience bloating this early with my last 3 nor was I even this big during the first few weeks. 
Any advice or suggestions?
Thank you!!
