I took baby aspirin when I got preg with my son and kept taking it through the first few weeks. It's supposed to help with implantation I believe. It's best for people that have multiple miscarriages. I didn't take it by advice of my doctor but probably should have. I had a miscarriage at 5 weeks a couple months before I got preg again.
Evening primrose is good for cervical mucous and actually helps regulate your cycle too~!
