Stretch marks or burst blood vessels?

Elana • FTM to twin girls born 8/6/18 ❤️❤️

I just noticed these last night and they are really only visible if I lift my breast up so the skin stretches a bit.

Are they stretch marks or burst blood vessels? The skin is smooth, there are just faint red lines under the skin. Hubby and I fooled around for the first time in 6 months the other night (pelvic rest sucks!) so he may have been a bit handsy hahah.

Thanks!
