Been trying to get pragnent ?

In angust, I had my 1st and last depo shot, during the few months, my boyfriend and I are want to have a baby. I was suppose to go back in a october for another shot, but i never did. It's now, December, I haven't got pragnent. I bleed twice, one in the began of October and began of Noverber, but it was a slide bleed for an hour after sex. I'm happy to say, I'm more active for sex, then when I was on depo. Could someone help me understand, how long it will take to get pragnent? I feel like I'm pragnent, but the pragnent test say negative. I feel my boobs hurt differently, I feel my lower back hurt and I feel cramps like my period is coming, but I only felt this only these last week. I'm dripping slim white sticky and Oder. For ever in the restroom this week. I hate to take another pragnacy test and be disappointed. Plus I have heartburn and acid digested and I'm always sleepy. It's only been like that for two weeks, now. I took home a pragnancy test, each week, i do a pragnancy test and two were negivtive and this week, this on came out positive. both line were faithed, so I'm hoping it's really a positive.
