Hi, I am almost 21 yo and the man I'm with is 20 years older than me. I am trying to conceive before he gets too much older so we can have a child of our own, he has 2 sons from his first marriage. In December I quit smoking so I could safely get pregnant and carry a child and of course after quitting my periods became all wacky and I missed mine January and now it came twice (brownish colored from January I am assuming and now my typical period which is now late). This obviously messed with my ovulation schedule so I'm curious whether I should use my old ovulation days or the new ones. And what can I do to raise the chances of conceiving without going to the doctor. There is nothing I dislike more than going to the doctor. Any help would be great. I am young but very mature and very ready for a child.
