Husband had a vasectomy

🫣 Let me start by explaining. My husband had a vasectomy July 2nd of this year. We were told that we would be in the clear to have unprotected $€X at minimum 6 weeks or 8 weeks maximum. Which we did par take in past the 6 weeks. My cycle is due anywhere from 3 days ago to now. This app said 2 days ago and then it changed to today. However I have been having period cramps, back ache and feeling wet like I’ve started but there’s no blood for the past 4 days 😬. I’m too scared to test. We have 3 children and knew we were done hence the vasectomy. If you’ve gotten this far thank you for sticking it out. Has anyone experienced pms cramps and back ache 4 days prior to starting and their period just was a bit off schedule and ended up showing up? This has me freaked. I typically start the same day I get the cramps.!! Help
