Ttc for the first month?

well this is the first month of ttc, about 3 days after i thought i conceive after me and my partner bd i had a pinkish colour discharge straight after but nothing since, but i have had a slighty but noticebly sore left , i had bad heartburn for 3 days, very bloated for the past 2 days. i was gy but that worn off. i have had cramps maybe 3 times a day for about 4 days. but 2 days ago i took 2 pregnancy tests and both came up negative... do you think i should take another test yet or leave it for another day or so?
