HELP!!

I missed my last two periods but I'm not on birth control or do alot of physical activity so it didn't make sense to me that I missed two periods and I'm 48 days late to this one I had sex a month ago and the condom broke we didn't figure it out till like an hour later so I thought I could be pregnant but then I had some discharge so I just assumed my period was coming but that was two months ago and now I'm getting sick a lot so that's how I realized I haven't had a period in 3 months. Should I be worried?
