So me and my fiancee have been trying to conceive since October. I am very regular with my cycles but I haven't had a period since December! I've taken so many hpt that I'm about to lose my mind. I have gone to the doctor every month and have had negative tests there as well. I had a positive test last month but went to the doctor the next day and it was negative. I was supposed to start my period on the 16th but like the last three months it hasn't come so like I always do I took a hpt test today which is the 19 and still negative... WHAT SHOULD I DO??? I'm about to have a breakdown!
