Need advice...

So my husband and I recently decided that we were going to stop preventing pregnancy...not necessarily trying but also not using any form of BC. According to my calendar and CM, I ovulated last week. Hubs finished inside me three separate times that week. I’m supposed to start my period next week but the thought of me possibly being pregnant has been all consuming this past week. 😅 I feel like I’ve had some symptoms...but they could also be PMS symptoms. Sore breasts, irritability/crazy emotions, some mild abdominal pain, and fatigue. Anyway, just needing some thoughts on the likelihood that I may actually be pregnant or if I’m crazy and overthinking things. Also don’t know if I should let him know about what I think could potentially be going on or just wait until I know for sure.
