I'm worried. I recently became sexually active again but haven't had sex since my period came 3 weeks ago. I typically have periods about 5 weeks apart, sometimes longer as I'm very physically active (and occasionally I spot for a day or two midway through or a bit before). All sexual intercourse took place 4-5 weeks ago and condoms were used.

I've had some light blood for many days now- probably around a week?- and today it was heavy enough to need a liner. I'm still 2 weeks early for my period. Could I be pregnant? What is happening?

I have very, very little money and I'm uninsured, so I really need some self-help advice (instead of a "see a doctor" deal). I am not typically sexually active and I haven't seen an OBGYN for at least 6months and I doubt I will be able to afford one for another year... please give me some practical advice. Thank you so much.
