normal or not?

Sommer
Hello so the last couple of my months my period has been really weird.... some months it's late and others it's on time but very light. Period blood isn't normal color it's mostly rosy pink... my boobs are leaking and getting bigger. This month my period is late again about 3 days late already... I am so bloated I look about 9 months pregnant! I have been trying to lose weight so I've been eating healthier and I weighed myself this morning and I have went up about 10 pounds. Something doesn't seem right in my opinion. Can someone please help me and give me some advice? I have taken pregnancy test which were all negative. Just worried something is wrong.
