Worried about my lil man

I been sick and taking medicine. Havent really been feeling him flutter around. Cant wait to see him Wednesday and make sure he's ok. Been very stressed n sick. Lost my grandma this morning. Gonna be a long week. Im almost 16 weeks. I feel like i should be feeling kicks already. This is baby #4 for me. Prayers that he's ok in there. I try to tale pregnancy safe meds but cant always be sure.
