Genuinely unsure...

My SO and I have been using Conceptrol for the last almost 2 years after getting my 2nd Mirena removed due to horrific side effects and wanting a non hormonal option. He still withdraws every time even with the gel, and we do not have sex when I'm ovulating. My cycle has ranged from 32-38 days and recently (last 6 months) been a week later than the previous month every time. My last period was Feb 11th-16th. Glow said I should've had it this past week March 16th-20th. I have been cramping randomly off and on the last week, I'm thinking maybe it's just late but I genuinely am unsure if I'm stressing out making it worse or if I could be pregnant. Any opinions/experience would help :)
