Getting pregnant

Meagan
My partner and I have been trying since June. We have used a syringe, soft cups, pressed and the stork. I'm hoping timing was off the last time and that's it. We also changed sperm donors the first one smoked a lot of pot....a lot lol. I know that lowers sperms mobility. Any other tricks anyone has??? I'm also taking prenatal and drinking pre mama the days I'm TTC...helpp
