could it be ?

Laura • hi im laura we have a little boy who waa 12 weeks prem . i am currently wanting to start ttc.

Ok so last week i had 2 random days of spotting followed by brown discharge which has randomly stopped today. I have been using opks since Friday which have all been negative . getting fainter day by day with the one I've just done only showing one line . I've had cramp on and off today and felt really tired. could ovulation be on the way or have I missed it we did BD last night and 2 nights prior.
