Hello so I'm not on here much but i need some help. So last month my period was 5 days late and I am not due to start in 6 days. Well for the last 2 weeks I've been nauseous, lightheaded and I've had some cramping in my lower belly, also certain foods seem to make me feel worse. I've taken 2 pregnancy test and both have come back negative. Any insight would be great. BTW I am gonna be 25 in November. I've been ttc for about 7 years now and no luck. I did find out that I had chlamydia about 7 years ago but was treated for it! Any insight would be great
