Husband pesters me about sex

So my husband and I have sex once every 2-3 days and sometimes I skip a couple days because I’ll be sick, have a migraine from hell or I just don’t want to have sex. But we have sex at least 10-12 times a month. I tracked it in Jan because I thought maybe I don’t have sex with him enough. We are 24 and 25 and we have 2 children under 3 years old. I am exhausted a lot and I’m still breastfeeding the youngest. I’m also 9 weeks into starting an antidepressant that I’m not sure if it’s even working. So needless to say you can imagine my headspace with all I have going on. Sometimes I just don’t want sex and it’s not a priority. Well yesterday we went to a sex shop and got some stuff and we had sex last night, well not even 24 hours later my husband is bothering me about sex saying we never have sex. To make things worse, I’ve been sick for 5 days now with a cough, headache, and my chest is sore from coughing all night. I feel horrible and I honestly would have had sex with him if he hadn’t made a rude comment. He mentioned we never have sex and he asked if I’m trying to have sex tonight? He says that as if we hadn’t had sex 3 times in the last week already. It’s annoying and turns me off the more he says that and begs for sex. Are we not having it enough? I think considering our situation we have sex pretty regularly and more often than my friends and their husbands.
