So im on my 4th cycle day, I should be off my period in maybe two days. If i were to have sex on the last day or when its compleatly over would that increase my chances of getting pregnant? Or do i really have to wait for my ovulation date, which is hard for me to predict. I havent bought the ovulation test packets yet. And if i were to get pregnant, can i loose weight while im prego?? I want to loose weight first and have a healthy pregnancy for me and the baby. But it just kinda suck's because i have been struggeling with weight my whole life. i have about 80 pounds to loose and so far ive just taken care of 5. so 75 pounds to loose.. Im so ready to start a family so I need to loose this weight!
