Ugh been hurting since yesterday in my stomach and back its like a sharp pain along with pressure and just now sitting here on the couch waiting to go to work I got this sharp pain and then got lightheaded at the same time. Any of you other mommies have this happen? My job is being butts about me coming in trying to talk like they don't care if I stay out but trying to use the pitty party for me to come in all at the same time. Ugh I hate my job I wish they understood what I go through with this pregnancy it's definitely not a normal one for me sorry but I don't choose that
