First question- Okay, so i started my cycle on the 3rd of this month like every month... My cycle has been consistent/ normal for about 4 months now lasting about 7 days (i had m/c 03/23) of this year😔 Well this month when my cycle started it was on the 3rd starting out painful and heavy 2days in i started spotting really light leaving my "period" to last me only 5 days... The flow was different etc. I started too wonder if i was m/c again cause i get scared every month for cycle since i m/c back in march... Then i thought maybe implantation? or just a change in my flow. Has anyone had something similar happen and turned out pregnant? I have felt a little off, headaches, slight nausea, fatigue etc. But my iron is low and i dont see the dr. For another 2 weeks ... Opinions? Anyone experience anything similar?
