Waiting and waiting

This is my third month ttc and first month trying preseed. We also used clear blue opk and looks like I ovulated on day 15. Today is day 22. I have sore breasts but not totally sore and a ton of gas last week that seems to have stopped. Breasts are still sore and feeling bloated the whole time. The "insights" keep telling me these are symptoms of AF coming which is discouraging. I don't remember having these symptoms before I started trying but maybe I wasn't paying attention and they were always there. I am 35 and scared I'm not going to get pregnant on my own. 😕
