TTC; needing some advice!! A little TMI

Jessica

My period was 3 days late this month; And it wasn't a normal period...And now during intercourse it feels like my cervix is closed. Like I feel pressure. Could this mean I'm pregnant?? I took a test the day my period was supposed to start 3/9/2020 and it was negative. Could that have been implantation bleeding and it's too early to test?? Help. Please!! 🙏🏽🙏🏽🙏🏽
