This is the reason so many women “have periods” while pregnant & don’t find out for a while. It’s not an actual period but your hormone levels aren’t high enough yet so you still have bleeding at 4, 8 & 12 weeks. I took a test last week that had a faint line but it was a blue rexall brand so i brushed it off as a false positive after starting bleeding, but my period was only “heavy-ish” (really only medium flow & was really only when i wiped) for one day. & has basically only been when i wiped for the last 6 days. I’ve been having lots of backaches & nausea for the past two days. I know the answer will be to take a test & i will tomorrow when it comes in the mail but I’m just asking for personal experiences with breakthrough bleeding. I’m convinced I’m dying or pregnant 🙃
