Weight and Stretch marks

Wondering if anyone else is dealing with my situation....
I gained about 40-50lbs over a short few months due to some medications I was taking. Yes, I eat very well. Yes, I worked out regularly. With gaining weight so fast I got a bunch of stretch marks! When we weren't getting prego I decided to stop my medications and try hard to lose the weight it made me gain....and then boom! Pregnant!
Now I'm 11 weeks and already have some stretch marks on my belly. Freaking that it's only going to get worse!  I've been lubing up with lotion ever since they started and nothing works! I know it hereditary and my mom definitely has tiger stripes.
Anyone have a bunch of stretch marks from either weight issues or pregnancy? How have you changed your outlook to be positive about them?
