hey everyone!

i had sex once last cycle and it was protected but near ovulation and i got a very weird period after it like it was all light to medium flow no cramps but still soaked pads (no clots) for like 3 days. my swollen boobs went to normal size and everything. but this cycle im already on cd 35 and there’s no sign of my period coming except for swollen boobs. could i be pregnant from previous cycle? i didn’t have sex at all this cycle.
