Im stressed out and worrying everyday my period is 4 days late i was due my period on the 19th, me and my bf have always used a condom (we check it after for any breakage and sometimes during) we even sometimes change the condom if it starts to feel a bit thin to be extra sure but my period is late and i cant stop worrying if theres even a chance i could be, ive taken a test and it came back negative bur i know they can be false, at first i had usual pms symptoms right before the 19th and i even wore a pad to bed i was so certain id get it my boobs are sore and swollen but still no period almost 5 days later :/ am i over thinking?
