pregnant or not tough spot

Lori

i am a mother of a 4yr old so remembering my first symptoms in that pregnancy is a blur but i do remember light spotting i am suppose to start my period in 2 days and the past 2 days at the same time around 9pm i spot very lightly just when i wipe after peeing. i would be happy to be pregnant since my daughter keeps rubbing my tummy and says her baby sister is in there. The only problem is the potential father he is my ex been thinking of getting back with him but my mother hates him for what he did (cheated on me while we were engaged) and im at the edge. Yes we slept together even after the fact of him being unfaithful but because i still love him and i cant sleep with anyone else it feels so wrong. He would be ecstatic if i was since doctors said his chances of having kids is very very low.
