Just been feeling off lately. My partner and I have sex usually a couple times a day and lately I've been pretty late or even missed a few of my pills. A few days ago I had a tiny bit of spotting of brown blood and very light cramps. Now my breasts are really sore like it even hurts to wear a bra, I'm extremely tired, I've been constipated and nauseous. Also I've been getting heartburn which is something I never have. According to my pills I should be getting my period in 4 days, so should I wait until then to test?
