Okay so my boyfriend and I are TTC. I will put my calendar below & the hearts are the days we had unprotected sex and he obviously had finished inside me. I’m not on the pill or anything, I took two tests (on June 3rd) and there’s a VERY faint second line(still obvious though) then I start getting excited and wait a couple more days to take another test. Then this morning (June 6th) I woke up spotting bright red with cramps & my bleeding won’t stop. I’m stuck at this point and don’t know what is going on. Any advice will be very much appreciated!
