Discrimination at work?!

Charlotte • 21🦄 X.III.MMXVII💙👪
I'm currently 21+5 and I feel like my manager is picking on me for being pregnant! He's told me if I have a doctors appointment (emergency or not) I have to make up the time that I've been at the appointment or forfeit my pay for that time. Also he's told me going to an emergency doctors appointment (after having a bleed) and not coming into work beforehand was inconsiderate to my other colleagues because their lunches had to be changed!!! I also still suffer from morning sickness, some days it's from when I wake to when I go back to sleep, and he's asking why I keep being sick even though I hate anti-sickness tabs... erm maybe because I'm pregnant and it's one of those things?! And I'm sure it states that I'm entitled to be paid for any antenatal care incl. doctors appointments?? (I live in the UK) Just frustrating because Im at a point where I dread going to work, anyone have any advice or am I just being over sensitive?🤔
