Could I be pregnant......?

I was depo for a while, and I missed my last appointment. Didn’t bother me much. My husband and I just started to use condoms. Well.. I got my period, it lasted about a 4 to 5 days, then a week later, it was back. Both times it wasn’t as heavy as I remember ((I had been on depo for about a year before I missed)) One after noon, my husband and I got a few minutes of alone time and made love, we forgot about the condom… I was worried, and told him I was going to go and get the morning after pill. ((We have 4 already, and money is pretty tight)) My dad ended up getting sick, so the morning after pill was forgotten. Its been about a month since that happened. And I have yet to get my period, I’ve taken 2 home tests already. Both in the morning, like the box said to. And both were negative.

Should I go and get a blood test, or is my body just being funky because of the year of depo
