I'm currently on the pill (levlen ED) and my boyfriend is always using condoms. Over the past few days my nipples have been extremely sore (so sore that I can't wear a bra), very heavy and I've begun noticing a white discharge coming from the centre of the nipple. I've been very tired/exhausted and eating a lot more than usual (especially sweet foods). Is it possible I could be pregnant? Or is it just hormonal? It's never happened before and I've been taking the pill regularly and consistently for a year or so. I'm not due for my period until next week and I tried a pregnancy test but it came up negative. Should I try it again? Or is it something completely different?
