Hello Ladies !!
I'm new at the " message board" experience so I hope I'm on the right one

I have a question that I'm sure you've heard before , but I need ALL OPINIONS / ADVICE ANYONE IS WILLING TO GIVE . I'm 31 with 3 children already and think I may be pregnant again . I have a regular 27 / 28 day cycle that I keep good track of - my last " normal " period was March 2nd . My dh and I dtd on the 13th and 16th ( what I believe was my very fertile period ) . I had some light spotting bleeding 12 dpo ( I don't think it was AF )
which would've been 2 days early for AF for me - it lasted 24 hrs. and not enough to need to use anything ( sorry TMI ) Since then I have had light cramps , nausea in the evenings , and sore/ sensitive bb's . I tested on days 10 dpo , 14 dpo , and today ( 18 or 19 dpo ) All BFN so far - what do you guys think ?? Have any of you gotten a BFP at any later dpo ?? Could I still possibly be pregnant ?? Thank you in advance for your help !!
