prior to the beginning of the series one of the main characters abandons her child, but the series starts as the parent is working hard on mending their relationship
Sarah's backstory is not abusive but very tragic. In Season 2 Sarah and Kira are constantly on the run, It's not technically abuse but pretty traumatizing for the child. Also Gracie is abused by her family in this season (esp. S2E5 and E9). In S3E2 Kira is being held by a Castor Clone
(Season 1 spoiler) Season 1 shows how Beth, Cosima and Allison are being monitored by people close to them. It's not technically stalking but still a break of trust and privacy.
In S2 ep1 there is a scene showing a farmer doing artificial insemination on a cow (the cow is very obviously fake but the scene can still be triggering).
A man who believes he is with his partner comes onto her suddenly and attempts to have sex after arguing with her, and said woman (who is not his partner but just pretending to be) looks shocked and exceptionally uncomfortable, but does not resist for fear of being discovered. He stops shortly after kissing her and pushing her against a wall.

S1E1: on Crave, the time stamp for the scene starting is 22:30, but it doesn't actually happen until just after 23min mark. It's over at 23:16. It mostly looks like foamy slightly pink soap, but it is projected onto the table and there is a close up of it foaming/dribbling from her mouth after for a couple seconds.

Helena is a clone who presents with flat affect, odd speech and later, hallucinations. She was trained to kill as a young child, so her inclination to violence either towards herself or to others are possibly a result of abuse. Her behavior is strange and markedly different to other clones - *spoiler* she is initially a villainous presence - but it is far from a dehumanizing portrayal of a person with psychosis.
Helena mainly selfharms which is shown in S1e3, e4, e6 and e9; she also has deep self harm wounds on her back.
S2E2: Tomas flaggelates himself
S3E2: Someone burns their skin at the end of the episode

S1 E1 in the opening scene there is a bit of shaky cam as it follows Sarah for a few moments.
Also in some scenes with Helena the camera goes in and out of focus to show her mental state.
S3E4: There's a bit of shakey cam as Helena walks around in the camp
During a particular scene in Season 4 a women being experimented on gives birth to a still born. The scene is semi graphic and triggering for anyone who may have miscarried or lost a child.
*SPOLIER* In S3, a girl is impregnated with embryos that come from her father's sperm (and another woman's ovary). So not really a relationship but technically she's still pregnant with her father's baby.
