So I have been trying to conceive since my miscarriage in December with no luck. I've been to the dr and had all of my levels checked and everything is normal. And my ultrasound also came back normal. The dr said just keep trying because nothing was wrong. Someone told me about taking robitussin. It's supposed to "thicken" the lining of your uterus during ovulation so it "sticks" I have also heard of taking geritol.... Anyone have experience with either of those?! Input would be fantastic !
