Cramps a week after intercourse

Me and my husband has been TTC for 6 months now. Last week we had sex, Tuesday and Wednesday I had cramps. I have an irregular cycle but I just had my period 2 weeks ago, and my cycles are always at least 30days( I've never had a 28day cycle). I know it's entirely too early know right now but it could be possible, right? I found out very early I was pregnant with our daughter. I started having really bad cramps 2 weeks after we had unprotected sex(we weren't trying and still using protection). I went to the doctor a week or so later and found out I was 3 weeks. I'm hoping it's the same situation. Did any of you ladies experience this before? Could I just want it so bad I'm seeing everything as a sign of pregnancy? I really do want this though lol
