I had protected sex with a condom on March 25 and started my period on march 28. There was no leaks in the condom and we pulled out. I haven’t had a period since March 28. All of my pregnancy tests have been negative. both at home and at a clinic. my boobs hurt a little all of a sudden and i have some cramps, like PMS cramps. but other than that i have 0 symptoms. Is it possible for me to be pregnant and not know? It’s been 4 months without a period and I have been stressing about being pregnant the whole time. I am 18 and on NO birth control. Please help me. Could I be pregnant? or am i having a phantom pregnancy by stressing so much about it?
