So sad.. I hate waiting, and this is alot harder than i thought *Cries* I just want get pregnant now and stay that way. I had a miscarriage and didn't even know I was for sure pregnant for 4 weeks.. I'm so upset. I have a question. How hard is it//is it easy or hard to get pregnant after a miscarriage? Like waiting till you stop bleeding//until you ovulate and start again and get pregnant? Or does it take months after and non stop trying every other day.. And another question 2 questions, is it possible to get pregnant while not ovulating? And can having a miscarriage make you unable to have kids after it happens. I've talked to the doctor and they won't check if me ot him are fertile still, even though we've been trying a very long time now. And I'm sick of it, sick of waiting, it's agonizing. I've been smoking (cigarettes and stopped smoking pot and only do it like once every couple weeks now but have been smoking both since 13-14 years old, and im now 18 and its pretty impossible to stop smoking cigarettes even with medicine and patches..) And I'm 4'11 and 73 pounds (normal for my height) and was anorexic when i was younger for a couple years, but was never bulemic(forcing self to throw up) i also sepf harmed for years, (cutting arms/thighs/ect) and used to hit my stomach alot, have had stomach problems since a baby with nausea bad, but went to have a check up when younger andnhad nothing wrong at the time. (Before smoking) I'm worried im unable to get pregnant(or easily get pregnant) any signs for that without having to get a checkup???? I have been diagnosed with bipolar and ect but thats another topic, i stresd out EASILY i have random panic attacks without even doing anything stressful. And when i stress, my stomach takes all the stress feeling, like clenching, it's extremely difficult to overcome this without medication and i would like to have a pure non medication pregnancy unless for like Zofran or tylonal which i abuse alot because of car sickness and acid reflux since i pretty much get constant nausea from multiple things. I also have a fear of blood taking, needles and throwing up but have decided to try to just stay calm during these things since pregnancy is more important to me. Please I need help asap..Let me know for those who read this far and for those who know for a fact and have done research/nurses or doctors. Thank you so much.. I would like multiple answers so I can just feel more sure. πŸ˜”β€ I really need some prayers (for those who are Christian) And hella big baby dust....*sigh*
