I need advice

2.04.18 so I am 5 days late for my period that bitch is like clockwork every month. My boobs are extremely sore I've had possible morning sickness but I've taken 2 tests both BFN obviously I know it tests for hcg and that it can take a while to build up but I just need to know if I am pregnant. Has anyone had a positive for pregnancy on blood tests at 5 days late? or have you had a negative that later became positive? I am curious as I would like to get a blood test done to find out 🤔but if it's not worth it I won't risk the needle!!! Any answers will help!!

UPDATE: 3.4.18 so AF came to say hello but then I still think I'm pregnant... I don't feel like I'm on my period other than these God awful cramps, my boobs are getting more sore as the days go by yet on my period normally they start off super sore and get less as the days go by... I'm still feeling really nauseous and all of that jazz... I'm wondering if this is even my period... it's quite light I usually have dark and think periods with lots of clots... this has been very watery light red not pink but light bright red and no clots it just feels so abnormal🤦
