I am having all of the symptoms from take action for me. Headaches, nausea (7hr after I took it), then nothing for a while. Day 4 I had some mild swelling in my hands from water retention (I got dehydrated, DONT DO THAT). It went away after a day of serious hydrating. Then day 6 lots of nausea and headaches and fatigue and spotting/ light bleeding (brown blood), mild cramps, sensitive breasts, and can’t sleep. I have also been a hormonal monster (everything from sad, to mad as hell, to excited, to anxious, to happy and very very horny). Oh and I’ve been stressed put of my mind. My period isn’t for 11 more days and I basically had sex on the day I was ovulating 🙄. I took the ECP pretty soon after sex. The condom broke and we didn’t notice for a while. He didn’t cum in me, but there was plenty of pre cum. I am not on any other birth control. Just my luck. How long is it supposed to stay in your system?? I need off this roller coaster.
