“Tenting”? 275cc under the muscle. Breast width was 11.5cm (Photo)

Thank you for your inquiry.   After viewing your photos, you may still have some residual swelling.   It is not uncommon at this time to have a small amount of swelling that will eventually resolve.    I recommend letting your surgeon know of your concerns so that he/she may address the issue directly with you.    

Hello. Thank you for your inquiry and congratulations on your surgery!
It is important to have an in-person medical assessment regarding this issue as it is difficult to determine virtually. Continue to update your doctor in the matter and follow their post-op protocol.
It is important to get cleared by your doctor before engaging in specific physical activity before the 3 month healing period has ended as the healing stage is crucial for healthy results.
It generally takes around 6 months to a year to see your final results. Your tissues will take time to relax and allow your implants to "Drop and Fluff" settling into place.
Our tips for recovery following breast augmentation are to wear a supportive sports bra for 3 months post-operative and refrain from lifting anything heavier than 10 lbs for 3 weeks as we don't want any strain at your incision sites. Make sure to keep the area of your stitches clean by cleansing with hydrogen peroxide daily. Showering is encouraged! But, no sitting in water for 2 weeks following surgery (no baths, hot tubs, pools etc.).

I do not see evidence of symmastia.  It is common to have residual swelling in this area early after recovery.  Of course check with your plastic surgeon.
