Curious, please answer

I dont want to take a test if I'm over thinking things.

Husband and I are not trying to get pregnant but not avoiding it either (no protection, kind of paying attention to cycle).

In june we had sex a decent amount during and near ovulation.

Late june I had a light 4 day period, lighter than usual.

End of july I had a 3 day period, the first day was seemingly normal then the next two days super light for my normal.

I have 1 pregnancy test in the closet, dont want to waste it if I dont have to.

I've noticed more emotions and feelings of depression on and off which is abnormal but I know that it's coming from distance with God. And Gods been helping me through that. But regardless, the emotional side I've noticed more.

Other than that no other real symptoms.

Thoughts? Take a test or just abrmomal periods?

Only other thing to note is my husband and I were not living together for a while and just moved in together in june, so I know more sex can change things with your period.

Thanks ladies!
