Preggo Sex

I'm 13 weeks pregnant and on progesterone suppositories. Which make me very dry down there. My husband and I haven't had sex since we found out. Which is fine with me because I'm a worrier lol. Well, we tried last night and only managed to get a little in before I just hurt too much, even with lube. I felt bad but honestly what can I do? Then today he texts me about trying again. Ugh. I feel bad but it's so uncomfortable for me and I thought he understood that. I'm just feeling ignored about my feelings physically and mentally about it. Any advice?
