Tubal & missed period…

I had my tubes cut & burned the end of December 2022. I’ve had a period every month since. Until this month. Something told me to track when I slept with my husband one day (July 31st, and to track the spotting I had on August 6th.) my period was due August 15th. The 29th I’ll be a week late from the first day of my expected period. Currently a pregnancy test is negative. I’m extremely tired, nauseous, peeing way too much for my liking, smells are horrible, constipated…I could go on. No sign of my period. I didn’t realize I missed it when I found out I was pregnant with my son in 2022 until my now husband pointed out my severe exhaustion and I tested. I was roughly 2 weeks late and only got a very faint positive confirmed next day by bloodwork. Same with my daughter in 2017 when I confirmed with her. I know tubals can fail for a number of reasons. And my app is adding up with the timeline of when someone who could have conceived would possibly implant spot and so forth. We were talking about a reversal but without it, so much could go wrong if my body fails this possible pregnancy. Thoughts???
