TTC help

Okay. I need Help!!!

My hubs and I have been trying since July 21 when I got my iud taken out. I was finishing my period when it was taken out. In August, my period lasted 3 days and a week early. This month, it came right on the normal time (4 weeks), but only lasted 1 day- Sept. 5.

We have been pretty good on baby making often during my ovulation (and based on this and another app, had sex ON my ovulation day).

I've been feeling weird in my tummy and had lower back tinge pains.

Just took a test today and it was negative.

Should I try testing again in a week or so, or just go with not preggers?

Needing advice!

When I had my 10 year old, we were pregnant within a month of trying! 😩
