Just thinking

I was just thinking, women who smokes, drinks, or does drugs gets pregnant unplanned EASY. Why can't women who wants to get pregnant just as easy as the women who doesn't plan on having babies? I'm a smoker, I smoke around 15 cigarettes max a day on average which is less than I used to. I don't drink anymore, and I have never did drugs. I'm surprisingly healthy for the most part except for being in physical pain and tired most of the time. We've been trying to conceive for 15 months now with no luck. My mom was smoking, drinking alcohol and doing heavy lifting up until she found out that she was pregnant with me. She didn't find out until she was 4 months pregnant with me, and I was an unplanned baby but welcomed and loved. Again why can't some or most women who are wanting to have children have a hard time getting pregnant? It doesn't seem fare, I'm wanting a baby so bad right now that I'm starting to hold and carry my realistic reborn doll that I use for photography(practice taking newborn portraits) more. I even bought a few cheap and used clothes and a few other baby things. I bought a $15 bassinet not only for the photography but for my doll, and the same with the $10 used bouncer. The $40 pack and play was actually bought for the intented use for a real baby that I took care of a few days a week until we stopped being friends with her mom. Now the pack and play has clean laundry in it that still needs to be folded and put away. Like why would God give a woman who doesn't want to have a baby at that moment a BFP with the chances of her having an abortion instead of blessing a woman who wants to be a mom. Don't get me wrong it's a woman's right to choose but I'm personally against abortions. If a woman was raped, didn't report it or go to the hospital and gets pregnant than I can see having an abortion. But just being careless, getting pregnant and having an abortion is in my OPINION just wrong, just look for a loving and caring family to adopt the baby.
