Hi! Im also about 4 weeks along. It is very normal for both of those things to happen. Ive had 6 kids ( and 3 m/c) and I do believe it happened with about all of them :) So dont worry. Its normal. Have a healthy 9 months!
it is normal to have the discharge as long as its clear or white. An dose not have a smell like a infection. Get a prenatal vitaman that has fish oil in it. I had that problem until I started taking them. ( I went a few days with out them an trust me... you can tell the differance.) You dr can give you script for it. Or you can just get a bottle of the fish oil gel tabs from rite aid, gnc, wal-greens, ect. I'm 12 weeks an its very safe.
