Hi, Last month i had symptoms like, period pain, fatigue, nausea and mood swings a week before my period came. My period came but it was very heavy which is abnormal for me as my periods are normally light. It also stopped suddenly after 4 days when i normally bleed for 6

Now im due for my period this wednesday coming (1st July) and have been having these same symptoms for the past 2 weeks. Except this time i have aching breasts (mainly my right breast) also they get itchy and seem to be a bit bigger as some of my shirts have gotten tight, i also have to keep checking to see if my period has come early as i have a leaking feeling. it isnt here but i keep getting a clear/white discharge.

I had 2 negative tests last month.

Could i be pregnant or am i just being paraniod?
Im also on the pill but i missed a couple in a row last month also.
