Am I pregnant or just hormone issues?

So I took my BC out around the end of June and made the decision I would not put it back in as I would like to conceive sooner rather than later. On July 1st I was given antibiotics to take for a week while I was also having af. Once AF left we decided to just start trying and we started going with what the app says about when I ovulate. It is now July 21st and my nipples hurt so bad, my breasts are sore, my Fiance says my nipples have gotten bigger and I now have Montgomery tubercles and more show up every day. I have to wait two weeks before a "missed" period. Has anyone had this and actually been pregnant or is this just cause I stopped BC?
