Could it still be positive?

For about a month now, I have been “avoiding pregnancy” due to health issues. Well this morning, my husband and I, were getting ready to head out and do some youth ministry at a youth detention center about 3 hours away. So he asks, have you gotten AF yet. I said “no, it’s not due until Tuesday,” well I think he jinxed me because I started spotting 30 minutes later. I didn’t think anything more about it but shortly after, I started running a low grade fever and started feeling nauseated. We drove the 3 hours and got to where we needed to be, ate breakfast/lunch and it hit. The nausea and then the actual barfing

I felt bad but I didn’t want anyone to worry. So anyways fast forward, I was good on the drive back home but started feeling it again, no sooner then I walked through my front door the vomiting started again. My husband told me to take a pregnancy test but when I checked, AF has come on full speed. I said all this to ask... Could it be possible for pregnancy? Lol (sorry for the short story)
