TTC

[Thawkins10]

Hi need some friendly advise.. 
31st Aug had my implant out during September I had my AF 3 times in one month!! Awful I know expecially when TTC. I use the Ovia app and during beginning of this month it said i was in my fertile window, so done the deed ;) about 6days after started experiencing flutters in stomach not feeling myself tired, moody ya know symptoms that suggested a pregnancy. So like anyone would get abit excited by this anyways today I thought I would do a pregnancy test this morning bfn for pregnancy and also done a ovulation test to which showed a line in the test line slightly faint.. as the day went on I had really bad stomach cramps and now have brown spotting when wipe!! Now getting very frustrated. Has anyone experienced the same and what does this mean?? Thanks in advance xx
