Need some advice!?!

Mook

Ok so my periods have always been regular like date to date...My last regular period was Dec. 1-7, I had a wacky period Dec. 25-29, the hospital told me it was only stress... my boyfriend and I have unprotected sex every time so after December we returned to our regular sex life. On Jan. 13 I started to bleed instantly after a heated session one afternoon, I took it as just a period also... I only bled for 3 days (Jan.15) which was like a blessing to me since my normal cycle is 7!! But now on Feb. 8 I have no period!?! I’m starting to freak out because I’ve been getting a lot of weird symptoms that I don’t get before starting my period and my period is always spot on. I’m not sure if I should begin to panic or not ? I need some advice... anyone willing to help?
