Pls help. I recently took a bc injection (for 2mths) after a normal period. My first period after the injection came normally (28th day) but was very light (i have normal periods for 5 days). The bleeding was on for 2 days (light) and then had a brownish discharge for another 12 days.
My 2nd period is due soon (today/tomorrow) but I have had breast tenderness for about a week. My breast have felt heavy and quite sore around the nipple. The tenderness is reducing but still there. This is new for me (the duration of the tenderness. I usually have tenderness a day or two before my periods and not so painful/heavy).

I have also put on some weight (about 4kg) since I took the injection.
I have recently taken to exercising and not sure if the breast tenderness is due to the exercise (not worn sports bra during training).
I am due for another shot of the bc injection and not sure if I want to ...Cos of the weight gain, tenderness, light period and discharge.

I have not seen my gp, waiting to see if my period will come and what it will be like this time
