Ladies 💜 I had sex about a month ago I think and it was my first time ever and I'm 24 years old ! My period the previous month was late. A couple of days so I thought I was pregnant! But then it started but only lasted 3 days I think which was odd my period usually lasts for 4-5 days !
Now this month i was supposed to start my period 3 days ago but There's no sign not even a simple spotting! This never happens to me never ! I'm alway on time and I'm always 4-5 days long ! Do you have any idea why this is happening? Should i be worried??? What should I do????? I'm a little nervous!!!!!
And let me edit this that my breasts have become massively huge and I'm sensitive with smells ! Please ladies answer if you can🙏🏻
