Pregnancy Fashion - 1st trimester

So I am 12 weeks and 4 days pregnant today which means I am just about done my first trimester!!! I am so happy to be almost done my first trimester. So far I still fit into all my pre-pregnancy clothes. I weighed myself yesterday at the gym and I weigh 125 which means I lost another pound. I am currently 2 pounds under my starting weight of 127. I really think that I have lost muscle which is why I weigh less because I definitely notice that I have more fat on my stomach, arms, hips, and back. I realize that weight gain is healthy during pregnancy so I am not trying to diet or anything.

Anyways during my 1st trimester I was able to wear my jeans very easily and even my dress pants to work which made dressing during my first trimester quite easy. My dress pants are slightly tighter so I didn't wear any super tight shirts but for the most part just wore my regular dressy shirts for work. In terms of my weekend wardrobe, I usually wore my jeans, a tank top, and a comfy sweater on top which totally covered any slight bulge or back fat.

I am trying to avoid spending money on maternity clothes so for my next trimester I am going to try and wear a lot of my spring/summer dresses and skirts. I have some empire waist dresses and a few long maxi skirts, as well as some other dresses that are made from a stretchy jersey material. So hopefully these dresses will get me through the second trimester. I think I may need to get some maternity pants for work because I don't think my dress pants will fit much longer. Plus I think my lighter dress pants are even a size smaller....I tried going to target last weekend to look for a bellyband to wear with my dress pants but they only had a large one which wouldn't work. 

Here is a picture of my pink maxi skirt I bought last weekend. I tried getting a size up so it would fit longer but they only had a size small. I bought it because it still fits now so hopefully I can wear it at least a couple of times and at the worst, I can always save it for next summer because I will probably have lost all the baby weight by next summer...

Please let me know if you have any other tips on what to wear during a spring/summer pregnancy...
