Hi, I'm 22 years old and not on any birth control...this was not an issue until now as was practicing abstinence. However, had unprotected sex right around the time that I would have been ovulating...I took the Plan B pills within 16 hours. Had unprotected sex again 5 days later and started what I believed to be my period the following day...it was 9 days early but I figured that it was due to taking Plan B. The bleeding was not as heavy as normal but not 'light' either and it was COMPLETELY done by end of 3 days...where as normally I would go for a full 6 days. It is today exactly 26 days after that initial intercourse (ovulation time and when I took Plan B...making it 21 days after start of that period) and I am so confused with where I'm at. I don't know if my body is just trying to set a new cycle due to Plan B? My breasts are soo incredibly sore and more swollen then is usual for me. Even my nipples were just so sensitive for about a week-and-a-half...right now are fine. Worst of all, last week-and-a-half I just burst into tears at absolutely nothing which is not exactly like me (I do cry from time to time but this unexplainable 'teary chest' feeling is not like me). But maybe I'm just not feeling my strongest as I have been feeling a little under the weather health wise the last couple weeks in general...some days freezing like crazy and then waking up drenched at night. I took 2 pregancy tests and the last reading today am not sure about. I'm not concerned about it being an STI as both of us are VERY conscious about these things and were tested. But I also don't "feel" pregnant...I know this does not mean much. Plus have been told a few times that for me to get pregnant could potentially be an issue. Any thoughts? Or am I just paranoid?
