work problems

I'm 7 weeks! I've had trouble with UTI and sickness, haven't eaten and had restless legs and struggle to sleep. I have called into work sick, then went in one day in agony and had to leave early to go doctors to find I had uti and needed antibiotics and had swollen bladder.
Since been off my colleagues are moody with me, barely talk to me - no longer include me in conversations and my manager talks to me in a snotty manner. They all are aware I'm pregnant. I'm not milking it as I don't even get paid for these days off, I feel lonely and uncomfortable. My managers are not approachable either. I don't know to make things right. I literally feel like they'd rather I quit but I can't afford that
