Pregnancy

I think I may be pregnant but can’t be 100% sure until “the time” to take the test. My period was from Sept. 8th - Sept 12th 2018 I had unprotected sex on Sept 15th with my bf he purposely ejaculated in me without me knowing until days later, on Sept 19th we had unprotected sex this time knowingly with the ejaculation part. We then had sex a third time on the 25th and the same thing happened. My ovulation period was from the 17th - 27th from what my Flo app says but I have been peeing like crazy and my breasts are so tender and sore , I’m not supposed to get my period for another 12 days and I know something is off 😫 if anyone has any opinions please help me🙏🏽 I believe he wants a child now and I would love too ❤️
