I seriously hate cycles! 😡 I don't understand..started spotting on the 17th.. Lasted 2 days had somewhat bleeding for 3 days and today it's bright pink kinda orange tint if thats even a thing lol and a lot of mucus like discharge with it. I'm pretty sure it was my period, could i be wrong? How heavy does it have to be to actually be considered a "flow"? Along with that, I have what they thought was strep but idk what it is. I'm taking amoxicillin for it. But I've also heard a lot of people get sick in the beginning when they find out they're pregnant. Sorry thats a lot of info, haven't been on in a while lol
