Cps question.

This is truly embarrassing & something I’m truly petrified about so please no harsh comments. I’m looking for answers & advice. I already feel like shit about it & keeps me up at times like tonight. I’ve been with my boyfriend for 2 years, before i even found our i was pregnant, my boyfriend & i got into a domestic fight. We were outside & i slapped him across the face for cheating (which in no way was okay for me to do) A women saw got my license plate & called the police. I was pulled over, questioned & arrested. Few weeks later i found out i was pregnant. We obviously at the time had a no contact Oder. The no contact order got dropped but i was told i need to take domestic violence class & be on probation for 1 year & 6 months otherwise go to trial and they’ll bring the women in the go against me along with my boyfriend. I’m kicking myself now in the ass for not going to trail but i took so much time out of work during that period i couldn’t afford it. Anyways was wondering since this situation happened & I’m now on probation will cps be involved with my family because of this past issue? They know I’m pregnant and know i live with my boyfriend. Will the state automatically send them because we live together & are expecting? After i have my baby I’ll only have give or take 6 months left of probation.
