Its been since november 9th start of af. And the cycle is at 41 days today. Ive had 3 negative tests, and one negative blood test a week ago. This is so frustrating. Always on time with af, never skipped, had some light cramping around time af was due. Has anyone else had low hcg levels and found out later they were pregnant? This would be my first. Thought i had a faint line on 12/11. Havent tested since. 😔
