Period due on the 14th

So I have been trying to conceive since July, my ovulation was to start on the 28th of August through to the 2nd of September. I and my husband had sex on Friday the 27th through to the 30th of August. I have been feeling tired, have sore breasts, have the urgent need to pee all the time and sometimes feel nauseous. My period is due on the 14th and I'm so nervous. I really want to have this Baby. I need some advise and good luck wishes too. Im so worried and anxious. 🙏🙏
