Is It a Bad Idea to Become Pregnant Before Seroma Has Fully Resolved?

I had a fairly large (10cm x 10cm) non-encapsulated lipoma removed from the back of my thigh about a month ago. Surgeon advised it had grown a little into my muscle. Post surgery i developed hematoma, and now have seroma. Incision has healed well and i have no infection. My surgeon has drained the seroma twice using a needle, and although it does refill, the fluid had reduced by half on the second aspiration so fluid is reducing. I am keen to try for another baby and wondered if i am safe to proceed?
