Vvfl??? Or lines in my eyes?

We had a natural miscarriage at the very start of May, I was just 6 weeks along but so excited and then devastated. we had it all confirmed that the baby had passed and my HCG levels went back down to 0 about a week after. We were told once the HCG was back down it would be ok to try again. I have been waiting about 4 weeks now for my period but knew that it might be late due to the miscarriage sending my cycle out. Just this morning however, I was feeling nauseous and I have awful acne and the biggest chocolate cravings! I though it might have been really bad PMS but took a test just Incase. Can anyone else see the vvfl? Or am I just seeing lines in my eyes? Has anyone else gotten pregnant after miscarrying without a cycle in between? Do you know if the risk of miscarriage is higher if it is just after a miscarriage?
