I am on clonazepam, zoloft, ambien, and abilify. Can this make my birth control pills (Junel) less effective? I had unprotected sex after my period ended on my week off of the pills, it ended early which was strange because it often lasts a long time. I am a day late for my period now. I have been feeling rather strange lately, had cramps at the same time every night (more intense than my premenstrual cramps), have been eating much more, had mood swings, breasts are tender, my privates look different, and I have a little bit of a belly now. I am a very thin person so this is especially unusual. I also noticed that in the bath tub my abdomen feels very strange, kind of light and floaty? Could someone please put my mind at ease? I am also peeing much more often.
