Or could these be signs of cheating?

[Daisypop89]

Stuck to his phone permanently smirking at it, absolutely delighted at the prospect of getting to go to his office this morning since working from home the last week (extra long shower, aftershave, 3 different hair products!), I have very unusual breakthrough bleeding which I needed to see a GP about and was advised to get a smear (I know this kind of bleeding can be a sign of STI).
The trip to the office this morning was supposed to be a flying visit to collect something but he has sent a few texts about how he'll be delayed and things are "slow". This will mean he left at 9 and wont be back till lunch. Also insisting we need things from the shops that we don't need, which he'll have to "stop and pick up on the way back". I know for a fact there is nobody else in his office building due to the obvious situation.
I have never been cheated on before so I don't know what to think. We have two very young DDs together and are otherwise happy and functioning very well as a family.

My DH has also been looking at his phone more than usual and often laughing/smirking. He isn’t cheating though, his friends are sending stupid memes.

@tarasmalatarocks absolutely, the fast talking and sounding anxious was very odd considering it should've been a boring trip to the office to collect a chair, I mean I couldn't think of anything more dull. And he is a massive over explainer at times. He often tries to explain away things before I have even questioned him on it, which I usually don't anyway. If I was constantly on his case then perhaps the over explaining could be a considered defensive move, but I am up to my eyes with the kids normally and even more so at the moment with all that's going on, so I have no time for analysing what he's doing.

Doesn't look good xx
