On the 26th I got a little pink circle. Than nothing for the rest of the day. For the other three days I have light bleeding. Usually I would have to empty my diva cup 3 times a day. So it was so random to barely have anything. Than I missed my period. Took a test and it said no. I keep deleting the period because I still haven’t started but why when I took a test 2 days ago, it said not pregnant. As well I had sex on the 23 before I got the 26th circle thing when I wiped. I thought it takes 7 days before in plantation bleeding? I’m confused. Kinda just stressed and will I start or no? What is everyone’s thoughts on this situation? Have you gone threw this? Also I’m feeling kinda lightly nauseous for 2 days. I started drinking lots of milk. If I drink a soda I feel icky.
