Husband help

Am I the only one whose husband isn't always in the mood? I mean we have a 5 year old and work different shifts so the BD can be a challenge. Yesterday I got a positive opk which I don't tell him bc I don't want to pressure him n Last night I waited up for him until 1030 (works late thursdays) for him to turn me down saying his stomach was hurting (son and I both just had a 24 stomach bug) but not him.. He ate fine and had no issues that I saw lol. Then I wake up this morning next to him (always up and gone by 715 am to bring my son to school and me to work) and still nothing. I thought morning would be better time bc they wake up hard and poke you with it but guess not lol. I almost feel embarrassed getting turned down😳 and don't even want to ask him. Any tips or advice? I don't want to force it and make him not want it even more but dang I need some lol.
