I’m tired

Currently at 21 weeks , feeling more and more tired as the day passes by and I can’t sleep well at night I have used up my leave and MC and currently starting to ask my gynae to give me HL everytime when I see him. But everytime I take HL I will hv those annoying colleague that will say things that make me feels very uncomfortable and it affects me a lot .. and slowly even my lady boss who actually is ok with me taking HL suddenly ask me to be CONSIDERATE to my other colleagues who has been working when I’m not ard. But the problem is when I’m not pregnant I’m the one who is covering working OT volunteer to work extra when there is no one who work extra but yet this is what I get . And I didn’t even complain that I’m tired when I work OT . But yet now , this one particular person who contributes nth in the team keeps complaining that he is tired when he DONT even want to work OT don’t want work PH. It’s making me very miserable . Making me feel that it’s wrong for me to be pregnant.
