2day light cycle......How is your cycle after D&C and laproscopic surgery

I had to have a D&C twice at the end of last year between Sep and Oct, with the removal of my right tube and my cycles are very normal now 30day cycles abut they dont last no more tha 2days with very very light periods.........it makes me think that im preggo.....but im not......I had 3 fibroids removed which in the past had me bleeding heavy from day one to day five.  I guess im not used to seeing a few spots........but I dont cramp or have much bleeding..........the only thing that affects me more is that my Boobs are extremely sore every month for at least 3wks and that since the surgery they have increased a half cup size.........not sure whats going on with my body.......but anyone had anything similar happen like this...........We have tried for about 1yr trying to get preggo and before my fiance ive tried about 3yrs.....so we have given it to God and when it happens it happens...........but anyone had this happen before.........ps..........I dont like asking everything to my specialist because she always want to to million dollar test that always come back the same ..........if I ever become preggo how in the world would I know if my periods are now 2days and very very light............
