Movement

So I’m 16 weeks and have been able to feel the baby move for a couple weeks now, but the last 2 days I just don’t recall feeling her move at all. Usually I can really feel her when I lay down for bed at night and last night I didn’t feel anything. I’ve been pretty sick the last 4 days and have been taking Tylenol cold & flu along with an antibiotic for a uti. Do you think the medicine is slowing her down and what can I do to try and get her to move? I’ve tried drinking cold sugary drinks and laying down and that doesn’t do anything. This is my second pregnancy and I never had this problem with my first daughter.
