I’m currently 4 days late on my period when I’m always on time maybe a day late. But the first day i missed i took test and it was negative so i don’t want to take any more yet but i keep having these little cramps like my period is coming and then it’s nothing so idk🤷🏽‍♀️ and I’m having headaches throughout the day with lower back pain and this past Friday and Saturday i was sick with vomiting and nausea. I’m just clueless.
