How much are you bleeding? I had spotting between weeks 5-7. Doctor prescribed duphaston and put me on strict bed rest. I noticed it happens more often when I walk around too much (like go out for lunch and then walk around 1-2hrs). Try resting more. If your gynae is concerned they will order bedrest for you and give you MC.
Did u walk excessively? Were u prescribed duphaston? My prev preg i bled red then slowly to brown for a long time
Mine was due to a tear previously coz i shopped a whole day tats y i bled quite like i had menses. But baby was ok thruout.
