Chelsea • I`m 20. Engaged. And TTC
I'm 20 and had a mc on April 6 a natural mc and my follow up was April 10 the dr said they(2) had passed and I should be fine. My fiancé really want a baby and so do I. Right away we have been having unprotected sex. How long should it take for me to find out if I'm pregnant again. And
