Not trying to be another broken record but curious on y’all’s experience

So the guy I’m seeing came In me during peak ovulation last month (took like 20 tests starting 10 days after that all were negative)

He came in me again a week before my “scheduled period” —which was 3 or 4 days late—got off my period last Thursday (9/9/2021). Today at work I could smell everything from a mile away, I’ve been feeling super tired and just off but I’m tired of stressing myself out testing because they were all negative and then I had a period.

Should I retest? Maybe my hormones are changing in my 30s? (I’ll be 31 in a couple of weeks)

Just left hanging out with him and I’m in, what the app predicts as, my peak fertility and he pulled out (we know we can’t trust how good the apps are with that unless we use ovulation trackers) so I plan to test again in 10 days, if need be, but just want some feedback from some women.

FYI, I see on here all the time young girls asking, to me, dumb questions and I’ve done the research—I’m educated but wondering, mostly, if:

A. I should retest after having a period

B. How many have gotten pregnant from the pull out

I’m just exhausted from the testing I did leading up to last months late period and I feel like I am just giving myself unnecessary anxiety.
