I had (unprotected) sex on the 18th, 19th, and 20th of January and I got some bleeding about 6 days before Af was due (medium flow) so now my cycle is 22 days late & every test i’ve took has been negative. I’m starting to get some symptoms such as really tender breast, slight cramps, and back aches. Does anybody know what’s going on?

FYI: I was supposed to get my period on jan. 31
