It may be talking about implantation bleeding but ur not suppose to get a period once u become pregnan if this is true we wouldnt be able to calculate how far along u are by ur last period
I'm not sure what website your on but on one i used, it told me milestones and the dates and it told me when i would have had my last period (2 weeks before conception), the date i concieved and then when i was 4 weeks it said this is when your period would be due and you missed it. It says you may experience implantation bleeding at this time also. Then it goes on to tell you when you can expect to hear the heartbeat, tell the gender, etc. That may be what they are talking about.
Like I search on Google a lot of questions and pregnancy symptoms and the app saids that this is my last period at like 4 or 5 weeks idk i think im saying it all wrong
Ive never heard that.. id like to know also?
