I have been taking the mini pill for the last 4 to 5 months. I haven't had any problems until recently. last month I missed two pills and remembered and took them the next day this month I forgot once and took itnine hours late. My husband and I are fairly active. Two weeks ago my nipples started getting really sensitive and poky. Then my breasts continued to become very sore and sensitive. In the last two weeks they have grown almost a whole cup size. I have been pregnant once before and that was the first indication. This time however I have had brown discharge, constipation followed by dark red blood if pushing to go. But never much but a few spots on a panty liner. I took a home test last week and it was negative. I have been moody and irritated and some cramping. Is this my body trying to have a period in the mini pill? If so why the sudden change in my breasts? I visited a dr office today just to take a urine test which was also negative and all they could suggest is testing again in a few weeks? I'm not sure that I am pregnant anymore but not sure why I am suddenly having changes on my pill.
