Just need some opinions...

Hey ladies! Just need some advice. My ovulation test was positive on April 16th. Hubby and I had sex about 3 times that day and then 2 days after that, so 3 days in a row. I get AF on a regular every month and I'm due for my period April 30th. I've been having hot flashes for 3 days, lower back pain, sore boobs and my bbt has been over 99.2 degrees when it's usually about 97.8. I took a pregnancy test and was negative but I'm thinking it's still to early to test. What are your opinions on the chances of me being pregnant?
