Looking for some insight/help

So I've done taking provera and no period after 2 weeks since last pill. Ultrasound has showed my uterine lining to be thin but yet my estrogen levels are normal. Progesterone still low. Doc has said for me to give clomid a go anyway. I asked about femara instead but he said ok to go with clomid ?? Anyway my concern is if I do become pregnant how will a thin lining factor into it ?? Will they give me something to support a pregnancy ? Theses are questions I have emailed him but thought I'd ask you gals 😍😍
