It’s been 7 months ttc. I’m 3 days late and it makes me nervous because I want to test, but every single time I think about testing or do test like I have in the past it’s either negative or I get my period. It took me 8 months to get pregnant last time(which ended in ectopic and left tube removed) I’m also nervous cause what if I am pregnant and it ends with me having an ectopic pregnancy like I did last August. I have been spotting a little pink, but that’s it so far.
