just started ttc this month

we jus had a bumb in our relationship of 3½yrs he will be 21 & I will be 20 in a few months and just last month I had a positive test an I went to the doctors bc after I took it we didn't go to the doctors right away bc he has work n gets back late well I was doing his grandma's hair I got a huge pain straight down my back next day I was bleeding but he said we going to continue to try we weren't trying at all till now.. but like I said he be busy so we have had sex a few times but not as much as I would want to to TTC but hopefully this is our month my period isn't till like the 28th but idk I'm always nauseous, n have back pain so idk if I'll be able to tell if I was but yeah barely trying again we did try awhile ago but stopped bc we had issues but we or he decided were now ready👣😇
