My period late is it high change pergenate

My last period and yours is about the same. My last period was on the November 20 (1st day period). I didn't have any pregnancy symptoms until a few days before I checked on pregnancy test. All i have was a few secs nausea about 3 days before i checked. I checked my pregnancy test on the 11 Jan 2021 and it came positive. I was 7 weeks late which is about one month and 3 weeks late. I get to know my pregnancy reaching to 2 months. If you're confident enough that you're not pregnant and your menses cycle is not regular then probably its normal. If not better take the test. It's better to know now rather then later. If you are pregnant must quickly take the folic acid as it will help the baby grow.
