So for the past couple months my boyfriend and I have been completely reckless. We haven't used condoms. I'm not on birth control and he doesn't normal pull out. Yet nothing is happening. I've taken pregnancy tests. All negative. I've been getting my period every four weeks. The only odd thing is I use to get it every 2.5-3 weeks and now it's every 4 but I do get this funky white discharge. I'm not sure if I could be pregnant and it's just not showing up on the test and I'm still getting my period or I just can't get pregant... any thoughts???
