so my boyfriend and I have been ttc for almost a year now with no luck I recently went to the doctor and he told me to take prenatle vitamins (which I've already been doing) and folic acid but he also told me once my period starts count 10 days and have sex on that day then every other day for a week so were going to do that but on glow it shows the 10th day will only be a 7% chance of pregnancy I was also gonna buy some preseed but being that it's only 7% that day should I still use it or wait until a day that the chances of pregnancy are higher
